Sid joined the band fairly late, so they may had already parted ways with McLaren by then.
They were with McLaren at least until the band disentigrated at Winterland in SF in 1977. He went back to England and left the band without any money.
Sid was dead by 78 I think.
And the lawsuit was in the 1980s maybe into the 1990s.
After the band had secured ownership of their songs, they reunited 20 years after that last tour (in 1997). Paul Cook (who was in the band before Sid and played as a session member on the lone album) rejoined the band.
Yeah...I’d have to do some research on the chronology. It’s been a while, hasn’t it?
