Paul McCartney and Stevie Wonder: 'Ebony and Ivory', 1982
Macca turned out millions of mawkish, maudlin little ditties in duet, and this was one of the poorest. Racism is like the keys of a piano, or something.
Bono and Frank Sinatra: 'I've Got You Under My Skin', 1993
There's no naysaying Bono's musical talents, but singing isn't one of them.
Hilary and Haylie Duff: 'Our Lips are Sealed', 2004
Possibly the only thing that could top this for sheer awfulness would be if the Olsen twins decided to do Mozart. Even then, it'd be a close-run thing.
Jennifer Warner and Bill Medley: '(I've Had) the Time of My Life', 1987
A lumpen, over-heated dirge from Dirty Dancing.
Willie Nelson and Julio Iglesias: 'To All the Girls I've Loved Before', 1984
Willie and Julio slap each other on the back about the number of notches on their respective bedposts. Yuk.
Glenn Hoddle and Chris Waddle: 'Diamond Lights', 1987
Hideous hairstyles, hideous suits and a hideous song.
Gwyneth Paltrow and Huey Lewis: 'Cruisin'', 2000
Gwynnie can actually sing, but this cover of the old Smokey Robinson song is dreadful.
Paula Abdul and MC Skat Kat: 'Opposites Attract', 1989
Not only singing, but dancing, with a cartoon cat: could it get any worse for you, Paula Abdul?Puff Daddy and Faith Evans: 'I'll Be Missing You', 1997
Cynical and emotionally manipulative "tribute" to the recently slain Notorious BIG.
Tom Jones and Cerys Matthews: 'Baby It's Cold Outside', 1999
A great song ruined by the painfully unpleasant voices of this pair.
