was Ron Wilson (no relation to Brian), who co-wrote "We're Together Again" with him for the Beach Boys, but the group's recording was left unreleased. In turn, Brian produced an ultimately unsuccessful solo single for Ron, a cover of "As Tears Go By", which was released by Columbia Records in September. Another artist that the group worked with was ex-convict Charles Manson, who was then seeking a career as a singer-songwriter. Dennis Wilson befriended Manson and was interested in signing him to Brother Records. Brian and Carl Wilson (not Dennis as is sometimes suggested) proceeded to co-produce several tracks for Manson at the Beach Boys' private studio located in Brian's home. These recordings remain unheard by the public. Over the summer of 1968, Brian attempted to record an arrangement of the 1927 show tune "Ol' Man River". According to music writer Brian Chidester, the session tapes "reveal Wilson conducting the Beach Boys to such extreme perfectionism that both he and the band seem at the end of their rope with one another". Friend and Three Dog Night singer Danny Hutton recalled that Brian expressed suicidal wishes at the time, and that it was "when [Brian's] real decline started". Afterward, Brian was admitted to a psychiatric hospital, possibly of his own volition. Brian's issues were not disclosed to the public, and sessions continued in his absence. Once discharged, Brian rarely finished any tracks for the band, leaving much of his subsequent Beach Boys output for Carl Wilson to complete. Regarding Brian's participation on the group's recordings from then, band engineer Stephen Desper said that Brian remained "indirectly involved with production" through Carl. Dennis said that Brian began to have "no involvement at all", which forced the group to "find things that [he] worked on and try and piece it together." Recording and content Older songs According to biographer Keith Badman, the 20/20 sessions marked "the emergence of Carl and Dennis as producers and of Steve Desper as the group's engineer. Desper is now part of the Beach Boys' fold and remains a chief engineer on their work early into the [1970s]." The two oldest tracks on 20/20 were sourced from late 1966 sessions for the band's unfinished album Smile. "Our Prayer" is a wordless hymn composed by Brian, while "Cabinessence" is a song written by Brian and Van Dyke Parks. Both tracks were given additional vocal overdubs by Carl and Dennis
