"Shambala", by Three Dog Night, is the song that spontaneously begins playing on the DHARMA van's 8-track tape deck when Hurley starts its engine in "Tricia Tanaka Is Dead". The beginning of the song is also heard earlier in the same episode in a flashback to Hurley's childhood. The song is heard yet again in "The Man Behind the Curtain" when Ben and Roger ride in the van.
