Roger Waters has spoken to BBC News arts correspondent Rebecca Jones for BBC Radio 4's Today Programme, in the run-up to the UK/European dates which we expect to be announced today. The BBC note that he will be taking the show to more than 30 cities from next May, including concerts at the O2 Arena in London, and Manchester.

In the interview, which you can read here, Roger explains the album's genesis, why he is reviving it now, and reveals an offer to get back together with his former bandmates.

They asked him why he is touring The Wall: "I decided to dip my toe back into the world of the touring rock 'n' roll person back at the turn of the century. Two years ago and the year before that I did a tour with the whole of The Dark Side of the Moon. So last year I was thinking, well, what am I going to do? Shall I just play golf or garden or go into politics, or have I got one more of these in me? I'm 66 years old now. So I thought, I think I have got one more. And I love to work. I shall certainly go on working but whether I'll do any more big tours I don't know. My fiancee said to me, if you're going to go out and do it again, do The Wall. That's what people will want to hear."

They also asked him if this was to be his farewell tour: "I wouldn't go that far, but yeah, it could be. I don't know what else I would do. In 2011 we're putting my opera on again in five cities in the south of Brazil. That's another thing that's very close to my heart. So there is always work to be done."
