1975 · Behind the Songs
The band barely wanted it on the album. Then it became the sound of the Hitchhiker’s Guide to the Galaxy.

The strangest six minutes in the Eagles catalog sit inside One of These Nights — released June 10, 1975 on Asylum and produced by Bill Szymczyk. “Journey of the Sorcerer” is a 6:40 instrumental built around Bernie Leadon’s banjo, with orchestral sweep and a brief fiddle passage.
Not everyone in the band wanted it there. Don Henley and Glenn Frey were unenthusiastic about including the piece, and the disagreement fed the tensions that would soon push Leadon out of the group — an account Don Felder later laid out in his book. Critics were split: Rolling Stone heard “bluegrass psychedelia,” while Stephen Holden dismissed it as “a bombastic instrumental [that] should have been omitted.”

Then the song found the audience the Eagles never imagined: the galaxy. In 1978 the BBC chose it as the theme for its Radio 4 adaptation of The Hitchhiker’s Guide to the Galaxy. Douglas Adams wanted music that sounded “spacey” without taking itself seriously; flipping through his own LP collection, he landed on One of These Nights and decided the banjo instrumental was ideal — strange, playful, and faintly alien.
The association stuck. Tim Souster recorded a fresh version for the show’s LP release; Paddy Kingsland and later Joby Talbot — for the 2005 film — made their own arrangements, and the theme returned for the 2018 follow-up radio series. An instrumental the band argued over became one of the most recognizable six minutes in science-fiction broadcasting.
