Rock legend David Crosby has undergone heart surgery after his doctor discovered a blocked artery.

The cardiac catheterisation procedure took place last week (14Feb14) 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 Woodstock hitmaker says, "I am very glad that I listened to my doctors and my family. It seems I am once again a very lucky man. Iā€™m sorry to have to move the dates, but I promise the music will be good when we do play them.ā€

An upcoming tour with Crosby, Stills and Nash, which is scheduled to begin early next month (Mar14) is expected to continue as planned.
