The 66-year-old Who rocker ' who will perform his group's classic album 'Tommy' at London's Royal Albert Hall ' thinks he only has a few years left of his music career and would like to make his current hobby more of a full-time passion when he retires.
He said: ''ve probably got two or three years left to do that kind of music and I want to make the most of it, because again I've been given a gift, use it, use it or lose it, so I'm going to do 'Tommy' at the Albert Hall.
''ll start painting then, I do a bit of daubing in my spare time, but I know that when I start that seriously it's going to have to be serious, there won't be room for anything else.'
Roger's show is part of the annual series of Teenage Cancer Trust charity shows he organises, which features a diverse line-up across several nights.
One headliner this year is Liam Gallagher's band Beady Eye and the veteran singer revealed he gets on well with the former Oasis frontman.
He told Absolute Radio DJ Dave Gorman: 'Liam Gallagher, I love him, everybody says 'Oh he's a bit difficult isn't he', I've always found him an absolute sweetheart.
'Liam's a very talented guy, very funny guy, very witty guy, and much cleverer than people give him credit for. Yeah, I love it... Liam is a real rock star. He is 100 per cent the real deal.'
