Crispin Glover [SEP] Music
In 1989, during a hiatus from films, Glover released an album titled "The Big Problem Does Not Equal the Solution, The Solution Equals Let It Be" through Restless Records, produced by Barnes & Barnes. The album features original songs such as "Clowny Clown Clown", odd versions of Lee Hazlewood's "These Boots Are Made for Walkin'", and Charles Manson's "I'll Never Say Never to Always" (sung in falsetto), and readings from his art books "Rat Catching" and "Oak Mot". Sample pages from these books are featured in the album's liner notes. Glover recorded a version of the Michael Jackson song "Ben" to coincide with the release of his 2003 film "Willard"; the song had been written for the sequel to the original 1971 version of the film.
