The movie, with the working title Freedom: George Michael, was to be narrated by Michael and set to feature Mark Ronson, Mary J Blige, Tony Bennett, Liam Gallagher, James Corden and Ricky Gervais.

The record was his second solo album, after the hugely successful Faith, and was arranged produced and almost entirely written by Michael, but did not feature him on the album cover.

It featured hits including Cowboys And Angels, Mother's Pride and Praying For Time and outsold Faith in the UK, where it went platinum four times but led to a court case with US record label Sony about Michael's frustration over how the album has been marketed. Michael lost the case.

A troubled life

Throughout his career, his drug use and taste for risky sex brought him into frequent brushes with the law, most famously in 1998 when he was arrested for public lewdness in Los Angeles.

His first solo album, 1987's "Faith," sold more 20 million copies, and he enjoyed several hit singles including the raunchy "I Want Your Sex," which was helped immeasurably by a provocative video that received wide air play on MTV.

The song was controversial not only because of its explicit nature, but also because it was seen as encouraging casual sex and promiscuity at a time when the AIDS epidemic was deepening. Michael and his management tried to tamp down this point of view by having the singer write "Explore Monogamy" on the leg and back of a model in the video.

He later said his late 20s had been a very depressing time for him after he lost his partner, Anselmo Feleppa, to HIV and his mother died some time later.

He said: "I had my very first relationship at 27 because I really had not actually come to terms with my sexuality until I was 24.

"I lost my partner to HIV then it took about three years to grieve; then after that I lost my mother. I felt almost like I was cursed."

The 1998 arrest received international media attention, and seemed for a brief time to jeopardise Michael's stature as a top recording artist.
