The band wanted to include famous rock stars on the album. Julian Raymond, the artists and repertoire representative for Hollywood Records, contacted Slash, Steve Jones, and Alice Cooper. Slash, who was a self-professed fan of the band's music, reportedly only asked for Wild Irish Rose as payment for his contributions. Bruce, who knew very little about the Sex Pistols or Steve Jones, declined to show up at the studio when Jones played his guitar part for "Piggy Pie". Although not knowing much about Alice Cooper either, Bruce decided to fly to Arizona and coach Cooper on his parts. Bruce and Clark also met George Clinton, who was staying in the same hotel, and recorded his voice in his room, but it did not fit anywhere on the album.
