improved dramatically. However, Leadon was becoming increasingly unhappy during the making of the album. He wrote three of the nine songs, none of which was released as a single. He was unhappy with the more rock direction of the band that Frey preferred, at one time walking out of a meeting to discuss which take to use after the recording of a rock track. Leadon would leave the band in late 1975, after the album was released. Frey also began to sing less as a lead singer starting with this album, singing solo lead on only one song ("Lyin' Eyes") and sharing lead vocals with Henley on another ("After the Thrill Is Gone"). Henley later said: "[Glenn] was generous in that respect ... If I began to do more than he did, it was because if someone had a strong suit he would play that card. 'You sing this, you sing it better,' that kind of thing." Randy Meisner sings lead on two songs, one of which, "Take it to the Limit", a composition he co-wrote with Frey and Henley, was released as the third single from the album. It is the only Eagles single on which Meisner sings lead. Track information "One of These Nights", "Lyin' Eyes", and "Take It to the Limit" were released as singles (information on these songs may be found in their respective articles). The following are some of the other notable songs in the album.

Adams said he had wanted something that sounded "sci-fi" while at the same time suggestive of a traveller, so this banjo-based instrumental struck him as ideal. "Journey of the Sorcerer" was used subsequently for the television series in 1981 (albeit re-recorded), the sequel radio series produced by Above the Title Productions for the BBC in 2003 and 2004, and (re-recorded once again) for the film produced by Disney/Touchstone in 2005. The original version from One of These Nights was used for all original transmissions of all five radio series, and a further version was used for the sixth. The TV adaptation of the series, and also an additional version released on LP record, used an arrangement by Tim Souster. The CD releases of radio series transmitted
