Fleetwood Mac has said it “looks forward” to its day in court after being sued by a disgruntled band member.
Guitarist and songwriter Lindsey Buckingham claims he was told five days after the group appeared at Radio City Music Hall in January that the band would tour without him.
The tour began earlier this month and Buckingham was replaced by Mike Campbell and Neil Finn.
Buckingham says he is seeking his share of tour income – at least $12m (£9.1m) – because he still wants to perform and is able to.
Band spokesperson Kristen Foster said in a statement: “Fleetwood Mac looks forward to their day in court”.
Bandmates Mick Fleetwood, Stevie Nicks, Christine McVie and John McVie are named in the suit.
Fleetwood was quoted in Rolling Stone in April as saying the band split with Buckingham because “we arrived at the impasse of hitting a brick wall”.
He added: “This was not a happy situation for us in terms of the logistics of a functioning band.
“To that purpose, we made a decision that we could not go on with him.
“Majority rules in term of what we need to do as a band and go forward.”
Buckingham told Rolling Stone magazine that he was informed by the band’s manager that “Stevie never wants to be on a stage with you again”.
He added: “Am I heartbroken about not doing another tour with Fleetwood Mac? No because I can see that there are many other areas to look into.
“The one thing that does bother me and breaks my heart is we spent 43 years always finding a way to rise above our personal differences and our difficulties to pursue and articulate a higher truth.
“That is our legacy. That is what the songs are about. This is not the way you end something like this.”
Lindsey Buckingham originally joined the band in 1974 with then-partner Stevie Nicks, teaming up with Mick Fleetwood, John McVie and Christine McVie.
Despite strained relationships and stories of wild hedonism, they produced some of the most memorable pop songs of the 1970s, with Buckingham helping to write, produce and perform on many of their most famous numbers.
They reached the peak of their success with the 1977 LP Rumours, which became one of the bestselling albums of all time, shifting 40 million copies worldwide.
