Did you know Roy Harper sang lead vocals on 'Have a Cigar' on Pink Floyd's 1975 album, Wish You Were Here?

Harper said that he was unhappy he had not been credited by the band for singing the song "for the first 10 or 15 years" after it came out. He also said he was not paid the agreed payment; he wanted tickets for life to Lord's (cricket ground) but received "a few hundred quid" instead. Harper had to hire a lawyer to resolve this grievance, which he called "ironic" and said it made the song (which is about rip-offs in the music business) into a self-fulfilling prophecy by turning the collaboration among friends into "the dirty music business".
