You can hear a MP3 interview with Kurt Kuersteiner talking about the Radio Horror Hosts website (and OTR in general) on WBSM's SpookySouthCoast radio program. Kuersteiner is introduced as the second guest about five minutes into the show. (It's also available in streaming audio version if you scroll down to July 26, 2008 Old-Time Radio Night, part 1).
Also from Kurt Kuersteiner, a new book: Old Time Radio's History of Horror!
