Unsatisfied with "Pet Sounds" collaborator Tony Asher's lyrics for "Good Vibrations", Wilson first asked Parks to help him rewrite the lyrics to the song; Parks declined, stating that he didn't think he could improve on them. During the recording of "Good Vibrations" in 1966, Parks claims to have suggested to Wilson while attending a session to have the cellist play triplet notes. Impressed by the results, Brian Wilson soon convinced Parks to write lyrics for the Beach Boys' next LP, the ambitious but ill-fated "Smile". In preparation for the writing and recording of the album, Wilson purchased several thousand dollars' worth of marijuana and hashish for himself and his friends, including Parks.
