While appearing on Bob Fass's radio show in 1975, he caught the ear of Phil Ochs, who was impressed by the young songwriter and agreed to produce his first album with Folkways.
Walker recorded two albums for Warner Brothers under the tutelage of producer Nick Venet, and toured Europe in 1978 and again in 1986.
Midnight was when Ochs was supposedly changing his stage name to Train, but his inebriated behavior incurred the wrath of the Gerde's staff to the point where the waitress was no longer serving Ochs, amid the soon-to-be-suicidal folksinger's rambling tirades against, among other musings, "Johnny Cash, BEFORE amphetamines".
Having finished his set including his signature tune "Closing Time", Walker watched Ochs with apparent embarrassment from the wings.
An uncirculated monochrome videotape and an audience tape converted to a double CDR exist of the event.
