How about John Fogerty going around performing CCR hits?
Is he billed as "CCR" or "Creedence Clearwater Revival" or using his own name? Or sometimes what they do is rehash the original name, something like "John Fogerty's CCR", or even could be "Creedence Clearwater Revival Revival"....LOL.
I know can go and see something called "Buddy Holly's Crickets", performing songs like Peggy Sue and That'll Be The Day. Obviously Buddy Holly is not around any more, but are there any original members of The Crickets playing, and not just session musicians or whatever.
Paul McCartney or Ringo Starr might still perform Beatles songs in their tours, but they're certainly not using the Beatles name in any way. I know there's tribute bands, like Bootleg Beatles. Saw a tribute version of Nirvana a few years ago, called Novana, they were awful.
