During production the filmmakers discovered an untitled and unrecorded piece of sheet music Gordon had written in 1963. The song was taken into the studio and recorded in a session supervised by Gordon. It was arranged by director Pat Evans and music producer Eric Sampson to fit the style of "Surfer's Stomp" era Marketts sound and was recorded live to replicate the sound as closely as possible. Former Routers/Marketts drummer Randy Viers was brought in to play drums on the song. The session was filmed for the documentary and the resulting song (subsequently titled "1963") will be released in conjunction with the film, making the length of time between the writing and release of the song 55 years.
