Rolling Stones drummer Charlie Watts has died at the age of 80.

Watts, who joined the band in 1964, died at a London hospital, according to a statement from his publicist. He had recently withdrawn from a U.S. tour due to illness.

Bernard Doherty said his client was "a cherished husband, father and grandfather and also, as a member of The Rolling Stones, one of the greatest drummers of his generation."
