in the recording of The Notorious Byrd Brothers. Clark himself claimed during a 1988 interview for radio station KBSG 97 that he was involved in the recording of "Goin' Back" and some other songs from the same period, although he didn't specify what his contributions might have been. There is also studio documentation and eyewitness accounts to suggest that Clark contributed backing vocals to "Goin' Back" and "Space Odyssey". One of those eyewitnesses, John Noreen of the L.A. folk rock band the Rose Garden, has stated in an interview that he clearly remembers being at Columbia Recording Studios during sessions for the album and seeing Clark record his backing vocals. This has been corroborated by the Rose Garden's drummer, Bruce Bowdin, who has claimed that Clark's voice can be heard most clearly on the mono mix of "Goin' Back" which was released as a single. Conversely, the Rose Garden's bass player William Fleming, who was also there, recalled that although Clark was in the studio he didn't participate in any recording. Author and musician Ric Menck has remarked that if Clark is present on either "Space Odyssey" or "Goin' Back", his contributions are not obvious and must have been buried very low in the mix by producer Gary Usher. The Byrds' lead guitarist, Roger McGuinn, cannot remember whether Clark contributed to the album or not, but he has admitted that it is possible. McGuinn has, however, gone on record as stating that he wrote the song "Get to You" with Clark, and that the writing credits on the album are mistaken; they should have read McGuinn/Clark, rather than McGuinn/Hillman. However, in an interview published in the November 2012 edition of Uncut magazine, Hillman stated that he definitely had a hand in writing the song with McGuinn, although he was unsure whether Clark also contributed to it or not. Music Production Despite its troubled genesis, the album contains some of the band's most gentle and ethereal music, as well as some of its most progressive and experimental. In a 2002 interview, McGuinn said it was "kind of Beatles-inspired" and cited their album Revolver as an influence. Lyrically, it attempted to deal with many contemporary themes such as peace, ecology, freedom, drug use, alienation and mankind's place in the universe. The album, as a whole, represented the apex of the McGuinn–Crosby–Hillman songwriting partnership, and took the musical experimentation of the original Byrds
