Plans for the musical had fallen through and as a result, McGuinn decided to record some of the material originally intended for the production with the Byrds. Among the Gene Tryp songs included on (Untitled) was "Chestnut Mare", which had originally been written for a scene in which the musical's eponymous hero attempts to catch and tame a wild horse. The song was excerpted from the album and issued as a single in the U.S. on October 23, 1970, but it only managed to climb to number 121 on the Billboard chart. Nonetheless, the song went on to become a staple of FM radio programming in America during the 1970s. "Chestnut Mare" did much better in the UK, however, when it was released as a single on January 1, 1971, reaching number 19 on the UK Singles Chart and giving the Byrds their first UK Top 20 hit since their cover of Bob Dylan's "All I Really Want to Do" had peaked at number 4 in September 1965. The Byrds returned to the recording studio with Melcher sporadically between October 1970 and early March 1971, in order to complete the follow-up to (Untitled), which would be released in June 1971 as Byrdmaniax. Unfortunately, the grueling pace of the band's touring schedule at the time meant that they were not fully prepared for the sessions and as a result, much of the material they recorded was under-developed. Following completion of the album recording sessions, the Byrds once again headed out on tour, leaving Melcher and engineer Chris Hinshaw to finish mixing the album in their absence. Controversially, Melcher and Hinshaw elected to bring in arranger Paul Polena to assist in the overdubbing of strings, horns, and a gospel choir onto many of the songs, allegedly without the band's consent. Drummer Gene Parsons recalled in a 1997 interview that when the band heard Melcher's additions they campaigned to have the album remixed and the orchestration removed but Columbia Records refused, citing budget restrictions, and the record was duly pressed up and released.
