Purple Tape tracks for later albums and EP releases, the sole exception being "Rock a My Soul". This, along with the rest of the nine "missing" Purple Tape tracks, were released as Pixies in 2002. Artwork and packaging The title of the album is derived from "Watch What You're Doing", a song by Christian rock singer Larry Norman, that includes the line, "C'mon pilgrim, you know He loves you", which the Pixies quote in the song "Levitate Me". Of Norman, Francis said, "when I was 14 I really dug him. I dressed like him, I looked like him, he was my total idol." The artwork was conceived by Vaughan Oliver, with photography from Simon Larbalestier. The man in the "hair shirt" on the cover was a friend of Larbalestier's and the photograph was from a series of work Larbalestier was making based on The Temptation of Saint Anthony by Gustave Flaubert. Composition Music Come On Pilgrim showcased much of Pixies' variety and set up the beginnings of many trends in their music. It displayed Joey Santiago's innovative guitar leads, Kim Deal's sunny vocal harmonies, and Black Francis's vocal range, which varied from screaming to traditionally-sung melodies. A version of the song "Vamos" would appear on Pixies' next two releases: re-recorded with Steve Albini for their first full-length album, Surfer Rosa, and as a live B-side on their first single, "Gigantic". Reflecting on Come On Pilgrim in 2022, Black Francis noted: "I was listening to Murmur by R.E.M. a lot just before Come on Pilgrim and that was hugely influential on me as a songwriter. I’m going to be cocky and say: we were even better than Murmur." Lyrics Come On Pilgrim includes two songs partly sung in Spanish ("Vamos" and "Isla de Encanta"), which drew upon some of Francis's experiences in Puerto Rico. (Isla de Encanta is an alteration of the island's nickname, Isla del Encanto, meaning "isle of enchantment".) Two songs explicitly mention incest: "Nimrod's Son" and "The Holiday Song". "I've Been Tired" refers metaphorically to sex and rock & roll culture, and there are four songs with overt religious references or language ("Caribou", "Nimrod's Son", "The Holiday Song" and "Levitate Me"). "Caribou" is about reincarnation. "Ed Is Dead" is about a brain-damaged girl known to Francis who rode a bicycle with a transistor radio strapped to its handlebars, so she could play music.
