“Big Bottom” is the seventh song on the soundtrack This Is Spinal Tap, and arguably one of the most recognizable tracks on the album. It appears to be a direct parody of Queen’s 1978 hit, “Fat Bottomed Girls”, as well as a more general parody of the shameless sexuality of ‘cock rock’ acts, such as Whitesnake and Mötley Crüe, just to name a few.

“Big Bottom” is notable for its three bass arrangement, which are played by the fictional characters of the film, “David St. Hubbins”, “Nigel Tufnel”, and “Derek Smalls”. All characters contribute to the song by providing it with a driving force consisting of loud and deep bass notes and chords, replacing the standard guitar.
