The Cyrkle were originally a "frat rock" band called The Rhondells, but were later discovered and managed by Brian Epstein, who was better known as manager of The Beatles. John Lennon provided the unique spelling of their new name.
In the summer of 1966, they opened on fourteen dates for The Beatles during their U.S. tour. On August 28, they headed the opening acts performing prior to The Beatles at Dodger Stadium.

The Cyrkle is best known for their 1966 song "Red Rubber Ball," which went to #2 on the Billboard Hot 100 chart. It was co-written by Paul Simon of Simon and Garfunkel and Bruce Woodley of The Seekers. The band had one more Top 20 hit, "Turn-Down Day," later in 1966.
After the release of the debut album, Red Rubber Ball, they recorded a second album, Neon, in late 1966, and a movie soundtrack, The Minx, in 1967. They followed that with various singles and then disbanded in late 1967.
