Since Fleetwood Mac first started 50 years ago in 1967 they've sold more than 100 million records.
Today they celebrate 50 years since they first began.
"I always look at it - and look at that date, and that it's been worth a damn," said Mick Fleetwood.
The name Fleetwood Mac came in the middle of a recording session.
They'd laid down an instrumental, their first unofficial track together, and the engineer asked, "What are we gonna put on the box?"
"Peter goes, 'Call it Fleetwood Mac. John and Mick are playing on it,'" Fleetwood said.
The first album was called "Peter Green's Fleetwood Mac" which, Fleetwood said, made Green furious. "He was asked, they said, 'Why would you call the band Fleetwood Mac? Why did you?' he said, 'Well I pretty much felt that one day I would leave and I wanted Mick and John to have a band,'" Fleetwood said.
And in 1970 Green left the band.
Fleetwood Mac's biggest album was 1977's Rumours, which sold 40 million copies and was the soundtrack of the band's breakups.
Guitarist Lindsey Buckingham splitting with Stevie Nicks and bassist John McVie divorcing his keyboardist wife, Christine.
When asked why they stayed together, Fleetwood said, "Corny, but because they get a dose of it. They definitely get a mega dose of it, which is challenging, you know to be able to attain that with this gloriously dysfunctional story, which is us bunch."
