Cheap Trick‘s co-founding bassist Tom Petersson revealed on the band’s social media platforms he recently underwent open heart surgery in March. Petersson, who’ll turn 70 next month, explained why he wasn’t his usually animated self during the band’s Thursday night (April 9th) performance on CBS’ The Late Show with Stephen Colbert.

Petersson posted on Friday: “Hi everyone, You may have noticed that I was sitting down during Stephen Colbert’s Late Show performance last night. I had to have open heart surgery a month ago and am under doctor’s orders to take it easy. I’m currently recuperating and slowly but surely getting stronger every day. Can’t wait to get back to see all of you again soon. Tom”
