Frank Zappa stops by for an after gig radio interview at WBCN-FM, Boston, MA, on October 26th, 1978. Zappa apologizes for his lateness by producing a tape from the mixing board of the start of the prior night’s show of “Persona Non Grata” from North Shore Coliseum, Danvers, MA, followed by an interview. Another piece of fantastic Zappa history.
