Sonny And Cher concert advertisement, 1967

Sonny and Cher were scheduled to be 1967’s headline musical performers supplementing the more psychedelic “Happening” concert series which included Buffalo Springfield, the Electric Prunes, and Jefferson Airplane. Tragically, Cher suffered a miscarriage shortly before the show was planned to begin. To save face for a heavily promoted show, the duo’s agent and radio promoters convinced a reluctant Sonny to leave California for the show while Cher recovered at a hospital. After holding a last-minute audition for backup female singers, Sonny performed his first show ever without Cher.
