Jenkins headlined New York's Capitol Theater between 1949 and 1951 and the Paramount Theater in 1952. He appeared in Las Vegas in 1953 and many times thereafter. He worked for NBC as a TV producer from 1955 to 1957, and performed at the Hollywood Bowl in 1964. By 1949, Jenkins was musical director at Decca, and he signed – despite resistance from Decca's management – the Weavers, a Greenwich Village folk ensemble that included Pete Seeger among its members. The combination of the Weavers' folk music with Jenkins' orchestral arrangements became popular. Their most notable collaboration was a version of Lead Belly's "Goodnight Irene" (1950) backed by Jenkins' adaptation of the Israeli folk song, "Tzena, Tzena, Tzena". Other notable songs they recorded together are "The Roving Kind", "On Top of Old Smoky" (1951), and "Wimoweh" (1952).
