As was the case with many of Zappa's albums, "Apostrophe (')" was a melange of archival and recent recordings; side one of "Apostrophe (')" (1974) and "Over-Nite Sensation" (1973) were recorded simultaneously. The tracks on side two originate from various 1972 sessions with overdubs recorded in 1973 and 1974, except for "Excentrifugal Forz", where the drum track (played by Johnny Guerin) originally came from the "Hot Rats" sessions in 1969 (along with the bass and drum tracks for "Lemme Take You to the Beach" on "Studio Tan" (1978) and "Läther" (1996), although in the case of "Excentrifugal Forz" this is not actually noted in either the album liner notes or official correspondence), and "Stinkfoot", where the basic track, possibly originally known as "The Bass & Drums Song", dates from the "Chunga's Revenge" sessions in early 1970.
