I borrowed this idea from Glen Kellaway, so here is my list (in no particular order):
- Johnny Cash on “Girl From the North Country” (Bob Dylan). Not exactly a country song, but a beautiful duet.
- Kate Bush on “Don’t Give Up” (Peter Gabriel). A huge hit for both. Very poignant.
- Steve Perry on “Don’t Fight It” (Kenny Loggins). Perry didn’t guest very often, but this rocker he co-wrote with Loggins is on fire.
- John Lennon on “Fame” (David Bowie) Lennon co-wrote this song and plays guitar.
- Peter Cetera on “Hold Me ‘Til the Morning Comes” (Paul Anka). The ex-Chicago vocalist sounds great on this David Foster produced album.
- David Bowie on “Under Pressure” (Queen). Bowie co-wrote and performed the song from the early 1980s.
- Crosby & Nash on “Mexico” (James Taylor). David Crosby and Graham Nash were the voices if you want lovely three-part harmony. Not a widely known song, but perfect for these great voices.
- James Taylor on “You’ve Got a Friend” (Carole King). A big hit for Taylor on his own, he first sang with King on her Tapestry album.
- Ronnie Spector on “Take Me Home Tonight” (Eddie Money). A comeback hit for both singers.
- Mick Jagger on “You’re So Vain” (Carly Simon). In London to record her No Secrets album, Jagger added his vocals to the song and Simon to his long list of lovers.
- Merry Clayton on “Sympathy for the Devil” (Rolling Stones). Clayton, a famed R&B vocalist nailed this song. The request to attend the recording session got a very pregnant Clayton out of bed with sing with a band she was unfamiliar with.
- Stevie Nicks on “Gold” (John Stewart). The ex-Kingston Trio singer resurfaced with this late 1970s song, adding harmony vocals.
- Clare Tory on “Great Gig in the Sky” (Pink Floyd). Tory created the vocals for this Richard Wright penned song on Dark Side of the Moon and eventually received a co-writing credit.
- Elton John on “Whatever Gets You Thru the Night” (John Lennon). Lennon’s number one song. In return, he had to appear on stage and sing it with Elton John.
- Martha Davis on “The Monkey Time” (The Tubes). One of The Tubes best and most appealing songs. Davis, the sultry voiced leader of The Motels delivered a great harmony vocal. Unfortunately, was replaced with Michelle Gray’s vocal by producer Todd Rundgren (Gray’s husband).
