Will the Stones tour for their 50th?

New York — Rumours of a Rolling Stones 50th anniversary tour have been floating around for months. But if they're true, Mick Jagger isn't saying.

"I have no idea if there is going to be a tour," the Stones frontman said during an interview on Monday. "We haven't really discussed it. We are talking about if next year is the 50th anniversary, sort of. It depends where you are counting from."

Jagger joked that this may not be the golden anniversary for the band, since drummer Charlie Watts was with another group when the Stones first formed.

"I say to Charlie, 'I looked up the 50th anniversary of the Rolling Stones and you were not playing the drums ... That is so sad that you can't be in the 50th anniversary, Charlie, because you were not there on the date which was July or whenever it was,'" Jagger said, laughing.

The Stones finished their last tour in 2007.
