Frank Zappa wanted to use backup singers on the songs "I'm the Slime", "Dirty Love", "Zomby Woof", "Dinah-Moe Humm" and "Montana".

[2] During the recording sessions at Bolic Sound, Tina brought Ike into the studio to hear the highly difficult middle section of "Montana" which had taken the Ikettes a few days to learn and master.

[1][4] For example, "Dinah-Moe Humm" describes a woman who wagers that the narrator can't give her an orgasm and is ultimately aroused by watching him have sex with her sister.

[4] The cover was done by Dave McMacken as somewhat in the vein of Salvador Dalí's surreal imagery depicting a two-headed man sitting on a waterbed in a Holiday Inn hotel room surrounded by various objects like a Mothers backstage pass and a television set showing Zappa's face with slime oozing out of it.

[4] Rolling Stone magazine disliked the album, describing Zappa as a "spent force", and saying that his best work had been recorded with earlier incarnations of the Mothers.

[7] Over-Nite Sensation (1973) and Apostrophe (') (1974) are the subject of a Classic Albums series documentary from Eagle Rock Entertainment, released on DVD May 1, 2007.
