In the 1970s, the duo reunited several times. Their first reunion was Together for McGovern, a benefit concert for presidential candidate George McGovern at New York's Madison Square Garden in June 1972. In 1975, they reconciled when they visited a recording session with John Lennon and Harry Nilsson. For the rest of the year, they attempted to make the reunion work, but their collaboration only yielded one song, "My Little Town", that was featured on Simon's "Still Crazy After All These Years" and Garfunkel's "Breakaway", both released in 1975. The song peaked at number nine on the Hot 100. In 1975, Garfunkel joined Simon for a medley of three songs on "Saturday Night Live," guest-hosted by Simon. In 1977, Garfunkel joined Simon for a brief performance of their old songs on "The Paul Simon Special", and later that year they recorded a cover of Sam Cooke's "(What a) Wonderful World" with James Taylor. Old tensions appeared to dissipate upon Garfunkel's return to New York in 1978, when the duo began interacting more often. On May 1, 1978, Simon joined Garfunkel for a concert held at Carnegie Hall to benefit the hearing disabled.
