The Cyrkle was a pop band that met as college students at Lafayette College in Easton, Pennsylvania in the mid-1960s. Their business manager was Brian Epstein who, of course, also managed the Beatles; the affected spelling of their name was suggested by John Lennon. The group had the opportunity to open for the Beatles for some of their 1966 US tour dates.
“Red Rubber Ball” was their first and biggest hit (Billboard #2 in 1966). The song was written by Paul Simon and Bruce Woodley of the Australian group The Seekers. Simon offered the song to the group during the time they opened for Simon and Garfunkel on tour.
There are several other notable recordings of the song. The Seekers recorded their own version of the song in 1966. Simon and Garfunkel performed the song at Lincoln Center in 1967, the recording of which was released in 1997. The most notorious cover of the song comes from the Canadian punk group The Diodes. In an interview, Paul Simon had made disparaging comments about punk rock, so The Diodes took that as an invitation to record their punk cover.
While none of these covers features a key change, The Cyrkle’s version offers a half-step modulation at 1:21.
