David Crosby of The Byrds and Crosby, Stills and Nash has undergone heart surgery in the US.
The 72-year-old rock and folk veteran has postponed his upcoming sold-out California shows while recovering from the operation.
Publicist Michael Jensen told the City News Service that Crosby had a cardiac catheterisation last week, in order to fix a blocked coronary artery.
In a statement, the singer said he is "once again a very lucky man". Crosby had a liver transplant back in 1994.
He's expected to make a full recovery from the surgery but his planned gigs in California have been pushed back to April.
Crosby's convalescence is expected to be brief as he is due to reunite with the other members of Crosby, Stills and Nash on a new US tour, which begins in March.
