Like all other Marx Brothers MGM films, "Go West" has several musical numbers, including "As if I Didn't Know" and "You Can't Argue with Love" both by Bronislau Kaper and Gus Kahn, "Ridin' the Range" by Roger Edens and Gus Kahn, "From the Land of the Sky-Blue Water" by Charles Wakefield Cadman and "The Woodpecker Song" by Harold Adamson and Eldo di Lazzaro. (In this song, Chico, playing the piano, rolls an orange on the keys in sync with the melody.)
