i think the temptations or some old group like that were performing with all fake members but being promoted as the real thing. can't remember if the og members were dead or not or just locked out by some weird contract.
The Money Jungle -jazz trio of Charles Mingus, Duke Ellington, and Max Roach (actually, max may be alive...) Edit: max is alive. also, technically the album is called The Money Jungle, but many folks referred to this trio by that name after the album was released. sorry for the somewhat inaccurate info.
I thought about that group, but the original members are still alive (Xavier, Ricky, Charlie, Johnny, and that dark-complected one). When RINGO STARR dies, well... never mind, doesn't fit this description.
