The band Talking Heads went through problems over name usage--former members minus David Byrne finally called themselves "The Heads"--even though they performed a lot of the Talking Heads' music in concert...I guess it has to do with copyright on already-recorded music etc. but you'd think people could work out name ownership issues without suing each other...

as for the Steeleye Span album by former members I am sorry to hear this album is so bad, there seem to be a number of good musicians on it...
