The star also reveals a new track may well make it onto the band's forthcoming Best Of...

BONO has said that U2 remains his main ambition in life – despite his increasing role in world politics.

The singer has just returned from a tour of Africa with U.S. Treasury Secretary Paul O’Neill, and recently lobbied French President Jacques Chirac on the subject of foreign aid and third world debt. However, he told Hot Press magazine that politics doesn’t excite him the way music still does.

He said: “Nothing comes close to the feeling of waking up with a melody in your head and having a band like U2 to help you capture it. Politicians don’t turn me on, politics doesn’t turn me on, the way music does. I have a lot more respect for them than I used to. They work a lot harder than I thought…but I don’t want to be one.”

U2 are in the studio working on new material, which could be released before the end of the year, or early next.

“We set up in a disused bar in the South of France. Very punk rock and very like old clubs we used to play,” he said. “Maybe it was being in that kind of venue, but the music we started to make was very lo-fi high energy. One of these songs might make it onto our new ‘Best Of’ which comes out later this year.”
