Robert Agnello was the writer and creator of numerous pieces of music for "Pete & Pete" and wrote the Blowholes music for the "Hard Day's Pete" episode. The show runners originally intended to use the song "Mississippi Queen" by Mountain for the episode, but could not afford the song rights and instead asked Agnello to write a "sound-alike" version. Agnello's sound-alike song, "Marmalade Cream", was so catchy that he was asked to produce three other songs for the episode: "Summer Wind", "Piledriver", and "You Color My World". He also wrote "One Lousy" Dance which was sung by Iggy Pop and the Garbageman theme sung by David Johanson. Many incidental songs in the series were performed by Agnello and his band Lamb to Slaughter.
