Mick Jagger swaggered back to the stage on Friday in his first concert after undergoing heart surgery in April as the Rolling Stones kicked off a delayed North American tour.

The veteran British band opened its No Filter tour in Chicago at the city's 61,500 seat Soldier Field stadium, after delaying the 17-date U.S. and Canada tour to allow for Jagger's medical treatment.

Opening to a sold-out crowd, the band kicked off with the 1968 hit "Street Fighting Man" as the Stones frontman, dressed in skinny black jeans and a black and white jacket, strutted across the stage, singing and pumping his fist.

Jagger, 75, underwent heart valve replacement surgery in New York in early April, and in May reassured fans that he was back in shape by posting video on Twitter of him dancing in a studio.

The 1960s band, whose current members Jagger, Keith Richards, Ronnie Wood and Charlie Watts are now all in their 70s, has played more than 40 tours, making the quartet some of the most enduring and successful rock musicians of all time.
