Who wants to play “name an artist who was background on a famous song” that nobody knew? I’ll start with Mick Jagger singing backup on “You’re so vain” by Carly Simon.

OK. Stevie Ray Vaughn player lead guitar on David Bowie’s Let’s Dance

John Lennon sings backup and plays guitar on David Bowie’s “Fame”

David Bowie singing background vocals on Walk on the Wild Side

Jeff Beck co-write and played drums on Stevie Wonder’s “Superstition”
