The Cyrkle was a popular 60’s band who often appeared with the Beatles on their U.S. tours. But it was Paul Simon who gave them their biggest break when the Cyrkle was on tour with Simon and Garfunkel. The song Simon co-wrote was “Red Rubber Ball,” which the Cyrkle brought all the way to #2 on the Billboard Hot 100 in 1966. Released on Columbia Records, a commercial copy of the 45 is worth no more than $10.00, but a red vinyl promo copy can sell for $100.00 today.
