Eight Miles High

The Byrds released Eight Miles High as a single on March 14, 1966, and it was later included on Fifth Dimension. It reached number 14 on the Billboard Hot 100 and number 24 on the UK Singles Chart. The lyric is mostly about the group's flight to London in August 1965. The music was influenced by Ravi Shankar and John Coltrane, and Crosby had brought cassettes of both on the November 1965 tour.

The master recording was made on January 24 and 25, 1966 at Columbia Studios in Hollywood, with Allen Stanton producing. An earlier version cut with Al Schmitt at RCA Studios on December 22, 1965 was not released by Columbia, since it was not recorded at a Columbia-owned studio. It appeared in 1987 on Never Before, and Crosby said of it, "It was a stunner, it was better, it was stronger." The Byrds were McGuinn on vocals and 12-string guitar, Clark on vocals, Crosby on vocals and guitar, Hillman on bass and Clarke on drums.
