Barry Gibb version 
"Guilty" is a song originally recorded by Barry Gibb as a guideline to Barbra Streisand for his album Guilty. On which Gibb on guitar, Blue Weaver on keyboard and Albhy Galuten on synthesizer.
The demo however sounds like the others, and since Barry sings it in falsetto throughout he had probably not yet decided to make it a duet, (By contrast parts of "What Kind of Fool" are natural voice.) It was said to have been the last song submitted for the album.
