Back in the '90s, a local deejay (back when that term meant a radio personality who played records on the air, rather than a E’d-up millennial who dances around behind a set of turntables and a control board at a rave. Now get the hell off my lawn.) used to do a lunchtime “what do these three songs have in common?” contest. The only one I ever got was:
“Candy” - Iggy Pop
“Love Shack” - The B-52s
“Shiny Happy People” - R.E.M.
The commonality, of course, was the presence of Kate Pierson on all three.
(Pierson’s background vocals on the R.E.M. track have been cited three times already in this thread, but in 2008, 2011 and 2012. The statute of limitations on ninja-ing has expired.)
