Frank Zappa, notorious for recording everything, carried cassettes with him on the road. On one occasion backstage during the late 70's, Frank gave longtime fan Ole' Lysgaard a cassette which contained a dub of a live recording excerpt from a concert in Williamsburg, VA 11-1-75. Thanks to Ole', this excerpt has been forever immortalized as the content for 'Corsaga' number 4. Joe's Menage is transferred directly from the show master tape.
