Freddie Mercury's mother was watching the Olympic closing ceremony when her adored son's image suddenly appeared on a vast screen. "I cried out: 'Oh my dear boy, where are you?'" she tells me. "I miss him so much." A cheeky smile then spreads across her face. "They showed John Lennon too, but there was much more applause for my Freddie."

Freddie, born Farrokh Bulsara, the frontman of rock band Queen and charismatic solo performer, died in 1991 of AIDS-related pneumonia. He was 45. Jer Bulsara, who is 90 next month, has found immense consolation in his continuing popularity, yet when talking about him her voice still cracks with emotion.

"His passing doesn't seem more than 20 years ago," she says. "I still feel he is around because his music is played so often. It reassures me that he is still loved by people all over the world, but of course, none of them love him as much as his mother."

Mrs Bulsara, who lives in a purpose-built three-bedroom bungalow in Nottingham, is tiny, immaculate and rather stooped, but her brain is sharp and her kind eyes sparkle when she talks about "my boy". She is a practising Parsee, a religion that follows the prophet Zoroaster who arrived in India from Persia in the 7th Century. She is also deeply private and this is the first in-depth interview she has given. The reason is a lavish new book: Freddie Mercury, The Great Pretender, A Life in Pictures which is full of wonderful photographs, including several never-before seen images that span the rock star's life.

One can only imagine how hard it must have been for Freddie's devoutly religious parents to come to terms with their firebrand son. Fortunately, the love flowed both ways and Freddie seems to have tried to protect them from his excesses.

Indeed, Mrs Bulsara reveals a very different Freddie to the exotic, bisexual, wild-living, supremely talented performer the public knew. "Freddie kept a strict division between his work and his home all his life," she says.

"If I ever asked he would say: 'Mum, that is business, and this is family.' He was kind and very respectful to myself and his father." Her husband, Bomi, a former cashier in the British Colonial Office, died nine years ago, aged 95. His sexuality was not a subject Freddie ever discussed at home. Nor did he tell her he was HIV positive or dying of AIDS. "He protected us by never discussing these matters," Mrs Bulsara reveals. "It is quite different now, but back then it would have been hard for him to tell us and we respected his feelings." Did she visit him when he was dying? "Of course," she whispers. "He didn't have to say anything. I knew he was very ill."

Freddie was born in Zanzibar in 1946 and went to an English-style boarding school in India when he was eight. "We tried to instil good values into him, like respecting the family and giving 100pc to whatever he did and although he wasn't religious, he respected our ways." The Parsee faith believes in one invisible God and is founded on the three tenets of good thoughts, good words and good deeds.

"Freddie always loved to sing and set up a school band when he was 12. In 1964, as a result of the Zanzibar revolution, the family, including Freddie's younger sister, Kashmira, now 60, fled to the UK and settled in a four-bedroom terraced house in Feltham, Middlesex. Mrs Bulsara and her husband found it hard, not least because of the weather, but Freddie thrived.

Like most parents they wanted their only son to have a safe job. "Most of our family are lawyers or accountants, but Freddie insisted he wasn't clever enough and wanted to play music and sing," she laughs. "My husband and I thought it was a phase he would grow out of and expected he would soon come back to his senses and return to proper studies. It didn't happen."

Instead Freddie went to Ealing Art College where he studied art and graphic design. "I felt particularly sad when Freddie decided to leave home and move to a flat in west London," his mother continues. He was always playing music and an elderly neighbour complained about the noise so he said it was time to go. I told him I understood.

"He first had a flat and then a big house, also in Kensington, but when he wasn't away on tour, he would come home regularly. He always liked my cooking, especially my dahls, sweet and sour mince and cheese biscuits. When he was famous and had people to dinner, he'd sometimes ask me to make them for him.

"He was so generous, too. One day he bought me a complete set of antique silver cutlery. I didn't like to use it as it was so posh. He also invited us for meals prepared by his cook and made a big fuss of me."

Freddie had countless male lovers in his life, but the individual he called the love of his life was a woman. Freddie met 19-year-old Mary Austin, who was a PR for the Biba boutique, in the early 1970s. They were together for seven years and he later described her as his common-law wife.

He said she was the only person he truly loved and left his mansion, most of his wealth and recording royalties to her. He even took her home to meet his parents.

"She was lovely," Mrs Bulsara recalls. "I used to wish they had got married and had a normal life with children. But even when they broke up, I knew she still loved my boy and they stayed friends right to the end. I haven't seen her since he died."

Did she approve that he left her the bulk of his estate? "Why not?" she replies firmly. "She was just like family to us and still is."

During her friendship with Freddie, Mary had a relationship another man, with whom she had two sons; Richard, who Freddie knew, and Jamie, born shortly after Freddie's death. Her relationship with this other man didn't last and she later married a London businessman. She still lives in Freddie's splendid mansion

Within a couple of years of Freddie's death, there were significant medical advances in the treatment of HIV and AIDS. Some believe that if he had lasted a little longer his life could have been saved.

Mrs Bulsara has a more philosophical approach. "It was a very sad day when he died in November 1991, but according to our religion, when it is the right time you cannot change it. You have to go. God loved him more and wanted him with Him and that is what I keep in my mind. No mother wants to see her son die, but, at the same time, he has done more for the world in his short life than many people could do in 100 years.

"After he died my husband and I missed him so much we decided to move to Nottingham, where Kashmira (Freddie's sister) was living with her husband, Roger, so we could be close to our two grandchildren. I have settled in and I am happy up here. I take great comfort today in all the things that happen around Freddie. There are so many tribute bands and I have been about six times to see We Will Rock You [the Queen musical in London].

"I was also very happy with the 'Freddie for a Day' event," she adds. This annual event, which takes place on or around Freddie's birthday (September 5), involves people dressing up as Freddie to raise money for the Mercury Phoenix Trust, founded by members of Queen, which helps AIDS charities worldwide.

Mrs Bulsara is particularly keen on the new book, containing finely reproduced photographs of Freddie from when he was six months old until shortly before his death. It shows a goofy-toothed teenager -- "I tried to sort it out with braces but he didn't bother wearing them. Later he didn't want to do anything that might affect his voice" -- a flamboyant rock star and cross-dresser. It also includes a CD of an 1980s interview with Freddie.

Mrs Bulsara's face lights up as she tenderly turns the pages, putting the photographs in context and commenting, not always favourably, on his hair and clothes. "As a mother you think: 'What is this?'" she laughs, pointing at a particularly garish outfit.

"I often told him I didn't like his clothes and dresses, and tried to get him to cut his hair, but he would explain it was something you have to do when you are in the pop world and gradually I learnt to accept it.

"Whatever he did or wore, I always saw in him the same child I knew, I could always connect with him."

Not every mother could say that about their famous son.
