Longbranch Pennywhistle was a country rock/folk music band consisting of Glenn Frey and John David Souther, formed in the sixties. The duo played at Troubadour nightclub and released a self-titled album in 1969 under the Amos Records label. However, in 1971 this record label dissolved, and Longbranch Pennywhistle split up. Shortly thereafter, in 1971, Frey formed a new group called Eagles, with Don Henley, who he had met at the Troubadour. Glenn Frey and J. D. Souther would continue their collaboration even after Longbranch Pennywhistle's breakup; Souther contributed to several Eagles classics such as Best of My Love, New Kid in Town and Heartache Tonight.
