I guess they will keep on rolling forever!!

Stones plot album, tour in ’11
Keith Richards has confirmed the Rolling Stones are preparing to head back to the studio to record a new album, which will be followed by a 2011 tour.
The veteran rockers have stepped away from the spotlight since they completed their 144-date A Bigger Bang trek in 2007, which remains the highest grossing concert tour of all time, while their album of the same name was released in 2005.
Rumours of a Rolling Stones resurgence have been rife in recent months, and guitarist Richards has now confirmed the musicians will start recording sessions next month.
He tells BBC 6 Music, “Everybody’s ready to go out there again. Who said it should stop, and who said when? Only we will know when it comes to an end, with a crashing halt… After these many years working together, we have a lot of unfinished stuff to work on that we had to leave off the last album.
“And knowing Mick, as I do, he’s a very prolific writer. I have ideas (too) and we’ll put them together in December or January. We’re looking forward to working.”
