Back in 1987, my then-girlfriend (now wife) and I saw The Guess Who (no Bachman or Cummings) and Buffalo Springfield (no Stills or Young.) Yeah, basically two tribute bands, but I knew that going in. Tickets were cheap and we enjoyed the show anyway.
When Buffalo Springfield came on stage, some guy in the audience yelled, "Where's Neil Young?" One of the band members replied, "Didn't you hear the news? Neil went solo."
