Ex-Fleetwood Mac guitarist Lindsey Buckingham suffered damage to his vocal cords during “emergency” heart surgery, The Guardian reports. “I am sad to say that last week Lindsey underwent emergency open heart surgery. He is now recuperating at home and each day he is stronger than the last,” wrote his wife, Kristen, on Instagram. “While he and his heart are doing well, the surgery resulted in vocal cord damage. While it is is unclear if this damage is permanent, we are hopeful it is not.” Fleetwood Mac, which started in 1967, kicked Buckingham out of the band right before it was scheduled to go on tour. He later alleged in court filings that there were disputes over tour scheduling and solo performances. Buckingham was a guitarist with Fleetwood Mac from 1975 to 1987, and rejoined the legendary rock group in 1997. He wrote some of the top hits on Fleetwood Mac’s smash album Rumors, such as “Go Your Own Way.”
