Last Friday (Feb. 14), David Crosby successfully underwent a procedure on his heart. The singer is expected to make a full recovery.

According to Something Else! Reviews, a routine visit to his doctor revealed that Crosby had a 90 percent blockage in his left anterior coronary artery. He underwent a cardiac catheterization, in which two stents were inserted into the heart. Had the blockage remained untreated, he most definitely would have had a heart attack.

“I am very glad that I listened to my doctors and my family,” said Crosby, who’s gotten Rock Hall nods both with CSN and with the Byrds. “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.”

As a result of his health issues, Crosby has been forced to postpone seven shows that were scheduled for later this month. The two nights at San Francisco's Great American Music Hall have been moved to April 20-21. The five nights at the Troubadour in Los Angeles have not yet been rebooked. Earlier this month, Crosby had previously postponed shows in Chicago and Vienna, Va. However, his upcoming tour with Crosby, Stills and Nash, which begins March 4 in Richmond, Va., is expected to continue as planned.
