Traum first appeared on record at a historic session in late 1962 when a group of young folk musicians, including Bob Dylan, Phil Ochs, Pete Seeger, Peter LaFarge and The Freedom Singers, gathered in the studio at Folkways Records to record an album called Broadside Ballads, Vol. 1 [REF].
In 1971 Happy once again joined Dylan in the studio, playing guitar, banjo, bass, and singing harmony on four songs, which appeared on Bob Dylan's Greatest Hits Vol.
