Between 1990 and 2017, I interviewed a number of people who knew FZ – professionally, or otherwise. These included Arthur Barrow, Bruce Bickford, Terry Bozzio, Pauline Butcher, Warren Cuccurullo, Bob & Thana Harris, Mike Keneally, Martin Lickert, Robert Martin, Kent Nagano, Lisa Popeil, Craig ‘Twister’ Steward, Scott Thunes, The Tornadoes, Chad Wackerman, Denny Walley, Ike Willis, Albert Wing and Bob & Candy Zappa. The full transcripts of all of these interviews can be found in my book Frank Talk: The Inside Stories Of Zappa’s Other People (Wymer, 2017).
