Mick Jagger Is Feeling 'Pretty Good' After Heart Surgery

The Rolling Stones frontman underwent a heart valve replacement in April.

Mick Jagger is back in action and feelin' fine.

After undergoing a heart valve replacement surgery in April, which forced the Rolling Stones to postpone their North American tour, Jagger has spoken out for the first time since the procedure.

"I'm feeling pretty good," he told Rolling Stone. "Been rehearsing a lot lately in the last few weeks ... This morning [I did] a bit of gym. Nothing crazy. Then I go into rehearsal with the rest of the band."

Prior to his operation, Jagger apologised to ticketholders over Twitter for the delay of their highly-anticipated shows back in April.

"I really hate letting you down like this," he wrote. "I'm devastated for having to postpone the tour but I will be working very hard to be back on stage as soon as I can."

Wasting no time getting back into the swing of things, the 75-year-old hinted that the group would be playing some rarer Stones tracks for their upcoming shows -- though fans of the classics need not worry.

"Most of the time people don't want too much unusual. People like a little bit unusual. They don't want 100 per cent unusual," he said.

The surgery led the band to postpone their tour which was originally slated to begin on April 20, however, with Mick on mend they will now resume their tour on June 21 in Chicago.
