This piece was a studio jam featuring FZ (lead guitar), Tony Duran
(rhythm guitar), and Jim Gordon (drums) of the Grand Wazoo band, plus
Jack Bruce (bass), formerly of Cream. The composition is credited to
the three soloists: Zappa, Bruce, and Gordon. It was recorded at
Electric Lady Studios, New York City, in September, 1972. FZ later
said that Bruce was "very difficult to play with" and "too busy". The
Mothers performed "Apostrophe" in concert in 1974 and 1975.
