I've typical singer's jowls, a bit fat and soggy. If I was really vain, I would have a nip and tuck, but the knife isn't an exciting prospect.
Dancing as a thing to do is marvellous, but you've got to be bloody good at it. I was never good enough.
In the past, it wasn't any big deal for people with talent to hang out together. Now we have the celebrity age, which has made a lot of things harder to do.
I'm impressed with Ed Sheeran. I think he has a terrific point of view and a great mentality but I sense there is someone in the background saying to him, 'We need more love songs, Ed.'
You won't find me at parties or the openings of movies and I don't hang around with David Beckham and Kanye West. So the paparazzi leave me alone, which means that I can do my shows, write music and then live a normal life.
There are a million misconceptions about me but the greatest is probably that people think I'm the king of disco. I love disco but it is only one part of me.
The Seventies was a golden era. Back then we had some incredible talent with bands like the Undertones, the Rolling Stones and artists like Bob Dylan and Paul McCartney.
Fame is always a bit crazy. You spend so long banging on the door trying to get in that when it suddenly opens, it's a very strange feeling.

In the early Nineties, after my first round of financial problems, I started a studio in Kensal Road in London right at the time when no record company wanted to hear anything from Leo Sayer.
I must have 300 songs unreleased or unrecorded, lying around. I'm a production machine, it never stops.
As a former Mod my love affair with fashion has never waned and whenever I go on tour I am always desperate to hit the shops as soon as possible.
I have always preferred paper and ink to a computer screen and I still write most of my lyrics by hand.
I particularly love the silk in Jakarta, the shoes in Tokyo and the amazing cloth from Thailand and Malaysia.
There were people who went for serious mind enhancement, like Jimi Hendrix or John Lennon, although I didn't really need to do that. I was blessed with an incredibly fertile imagination.
I'm not this cuddly, jumper-wearing, good-guy. I'm not David Cassidy. I'm more Johnny Rotten. I'm more Donny Tourette.
After my second No. 1, my record company, Warner Brothers, gave me a beautiful present - quite unique at the time - one of the very first Sony stereos which had speaker and radio included so I could record the radio and build up cassette tapes of music, gospel singing, adverts, evangelists.
I've found an extraordinary thing happens where I flash an entire finished song. I could be walking along, say over that bridge, and I see and hear the whole thing, words and music.
