Rehearsals for The Rolling Stones' No Filter tour wrapped up in London Thursday.
The tour -- which was postponed in April when Mick Jagger underwent heart surgery -- is set to start Friday at Soldier Field in Chicago, but there is speculation they'll follow tradition and do a surprise club show before that.
The tour runs in the U.S. through August 31st in Miami.
