the title song. However, in an interview for Polish rock magazine Tylko Rock he said that he had not played any bass guitar parts or done any co-writing on "Apostrophe (')", only the cello intro. He reminisced, "So I turned up in a NY studio with my cello, I'm listening to [Zappa's] music, pretty awful, and just don't know what to do with myself, and Frank [Zappa] says to me: "Listen, I would like you to play a sound, like this... whaaaaaang!!!" So I did what he asked me to do. Whaaaaaang!!! That was all. That was my input to Frank Zappa's most popular record! [laughs]" Bruce had studied the instrument at the Royal Scottish Academy of Music and Drama and performed with it on some of his other recordings. However, Zappa has referred to Bruce playing bass on the track in an interview: "Well, that was just a jam thing that happened because he was a friend of (drummer) Jim Gordon. I found it very difficult to play with him; he's too busy. He doesn't really want to play the bass in terms of root functions; I think he has other things on his mind. But that's the way jam sessions go." Release and reception Village Voice critic Robert Christgau wrote in his review: "Disillusioned acolytes are complaining that he's retreated, which means he's finally made top ten, but that's just his reward for professional persistence. If anything, the satire's improved a little, and the title piece—an improvisation with Jack Bruce, Jim Gordon, and rhythm guitarist Tony Duran—forays into quartet-style jazz-rock. Given Frank's distaste for 'Cosmik Debris' you'd think maybe he's come up with something earthier than Mahavishnu, but given his distaste for sex you can be sure it's more cerebral instead." Apostrophe (') and Over-Nite Sensation, recorded with the same group of musicians, are the subject of a Classic Albums series documentary from Eagle Rock Entertainment, released on DVD May 1, 2007. In July 2016, the Zappa Family Trust released a CD of alternate mixes, different takes and live versions of material from Apostrophe (') titled The Crux of the Biscuit. It includes early versions of "Down in De Dew", which Zappa considered for Apostrophe (') but later included on Läther.
