surgically, stuck together, and then sculpted afterwards". Once completed, each song was played in exactly the same way every time, eschewing the improvisation that typifies most popular music in favor of an approach more like a formal, classical composition. French has stated that about three-quarters of the songs were composed at the piano. The rest mostly consisted of parts that were whistled by Van Vliet. In a few cases, part of the song was composed at the piano while others were whistled. Three of the pieces were unaccompanied vocal solos ("Well", "The Dust Blows Forward and the Dust Blows Back", and "Orange Claw Hammer") while one was a spontaneous improvisation ("China Pig"). "Bills Corpse" was titled for the emaciated condition that Bill Harkleroad suffered before leaving an LSD cult to join the band, and possibly to similar conditions Van Vliet created within the band's house. Van Vliet called the song "Dali's Car" a "study in dissonance". "Hobo Chang Ba" was based on Van Vliet's stories "as a young teenager in Mojave of going down and hanging with the hobos. He said they were really nice people and he got to know the regulars." Drummer John French states of "Old Fart at Play", "[it] was never intended to have these lyrics. This is the only other time I saw Zappa aggressively put on his 'producer's hat' and assert his will on Don. The original title to this song was 'My Business Is the Truth, Your Business Is a Lie'." The album's title was adapted from some lines in "Old Fart at Play": ". . . the nose of the wooden mask / Where the holes had just been uh moment ago / Was now smooth amazingly blended camouflaged in / With the very intricate rainbow trout replica." Several of the compositions include brief passages from other songs. Some were childhood reminiscences, such as Gene Autry's recording "El Rancho Grande", from which one of the guitar lines in "Veteran's Day Poppy" was adapted, or the "Shortnin' Bread" melody used in "Pachuco Cadaver". Others were more contemporary, such as the quote "come out to show dem [them]" from Steve Reich's "Come Out" used in "Moonlight on Vermont", or a melodic fragment from the Miles Davis recording of Concierto de Aranjuez used as the basis for the bridge of "Sugar 'n Spikes". The ending of "Moonlight on Vermont" also includes the refrain from the
