Deputy head teacher with a dreadful singing voice did not let that stop him recording his own version Frozen song to wish as a goodbye to his pupils leaving for secondary school.

Chris Hill dressed up as princess Elsa from the favourite Disney musical to sing his own re-worded version of the film's smash hit, Let It Go.

And while his rendition of the song might be packed with sentiment, well-wishes and motivational catchphrases, it is also painfully tuneless and, in turn, absolutely hilarious.

Chris Hill dressed up as princess Elsa from the Disney favourite Frozen to sing his own re-worded version of the film's smash hit, Let It Go, to his leaving year six class

Chris, 29, decided to say goodbye to his 'best ever' year six class at Bolton St Catherine's Academy by putting on a dress similar to that sported by the Disney princess before performing his own adaptation around various parts of his primary school.

He's seen in the form room, sports hall and playground, prancing around in an aqua blue and green dress reciting his own version of the song, called Off You Go.

His lyrics - to the tune of the famous song - were re-jigged to pay tribute to the youngsters, wishing them the very best for their futures.

Mr Hill's musical work of art started with him in full Elsa costume in what appeared to be the school's PE hall

As the song went on he moved around the school. He's pictured here singing in front of a whiteboard

It was played at the Greater Manchester school's annual prom, but then found its way online via YouTube, where it has since become a hit - having been seen 2,700 times.

Fun-loving Chris said: 'My year six classes have always been great and every year they get better and better, and this year six class have been great. 'They worked hard and got results.

'I found the lyrics to the song on the website and I adapted them so it would work for the school.

It was then time to hit his song's high notes from behind the counter in the Bolton school's cafeteria

The hilarious video was played at the Greater Manchester school's annual prom, but was later shared on Youtube

Since being on the video sharing website, it has become a hit - having been watched more than 2,700 times

School principal Lee Harris admitted he too was blown away by Chris' video, especially the effort put into it

'It was all filmed on a mobile phone and I have to praise my assistant's camera skills because she managed to keep it still while laughing. There was a point when we were filming and saw some children, we had to hide, they saw something going on, but didn't know it was me.

'Some people have asked whether I would be going on Britain's Got Talent but given the quality of my singing, I doubt they would be ready for me yet.'

He added: 'All the mums and dads were really happy to see the film. Some cried with laughter and really thought the words meant a lot.'

The iconic Frozen song Let it Go was one of the biggest selling songs of 2013. Chris altered the words to create his own version, Off You Go

As well as his long blue dress, the popular teacher even donned a makeshift blonde wig and tiny crown to complete his transformation into Elsa

But he suggested Chris sticks to the teaching, for now anyway - as he's far better with chalk in hand as he is with a microphone.

'Mr Hill and the team ensured the students have had an outstanding year,' he said.

'It was a pleasure to see the students and parents enjoying his rendition of Off You Go, dedicated to our marvellous year six students as they progress into the secondary phase.
