My dad Chip used to say that I came out of the womb singing. Because he was in the band The Tremeloes, we had guitars in every corner of the house and all his friends were 1960s superstars like Gerry Marsden from Gerry and the Pacemakers, the Searchers, Herman’s Hermits, and Marmalade. My parents were always throwing parties – it was a very rock ‘n’ roll and liberal upbringing.

I guess I was never going to be an accountant! Still, I could never have expected to become famous the way that I did. I got a part in the film , playing Roger Daltrey’s character’s son, and we had this song on the soundtrack called , which was written by Nik Kershaw and sung by me.
