Lindsey Buckingham has described his departure from Fleetwood Mac as "not my doing or my choice".
The band announced in April that they would tour without the musician, who wrote and sang on some of their biggest hits, including Go Your Own Way and Tusk. Buckingham had been a member since he joined the group in 1974 with his then-girlfriend Stevie Nicks.
Announced last month as Buckingham's replacement, Crowded House front man Neil Finn is now in the middle of the band's drama.
During a set at a campaign fundraiser for Democratic congressional candidate Mike Levin in Los Angeles, Buckingham was filmed speaking about his firing.
In the video, which was shared on YouTube and Twitter, he said: "It's been an interesting time on a lot of levels. For me, personally, probably some of you know that for the last three months I have sadly taken leave of my band of 43 years, Fleetwood Mac.
