Rock legend David Crosby has undergone heart surgery after his doctor discovered a blocked artery.
The cardiac catheterization procedure took place last week and the Crosby, Stills & Nash star is expected to make a full recovery, but he has been forced to postpone a string of upcoming California shows to concentrate on his health.
The 72-year-old singer says, "I am very glad that I listened to my doctors and my family. It seems I am once again a very lucky man. I'm sorry to have to move the dates, but I promise the music will be good when we do play them."
An upcoming tour with Crosby, Stills and Nash, which is scheduled to begin early next month is expected to continue as planned.
