The Rolling Stones are without a doubt one of the biggest names of all time when it comes to in rock music. And according to sources within the Stones inner-circle, they will have to do without the presence of drummer Charlie Watts.

Watts, who has been the drummer for the band since 1963, has reportedly left the band according to Undercover.com.

“The news does not come as a surprise. It was common knowledge that Keith Richards had to talk Charlie into contributing to the A Bigger Bang tour but this time it seems there is no calling Charlie back to active duty.

With Mick Jagger planning more Stones activity next year, the departure of Charlie will be a huge blow to the band. Charlie was the backbone of the band.”

Sources close to Watts have simply said he doesn’t feel like doing it anymore. His departure comes just three years short of the band’s 50th Anniversary.
