Fred Gwynne aka Herman Munster- knew, as did the producers/directors of the CBSRMT, that he had the perfect,deep sonorous voice for radio ... that added to his timing, slow and  resonant tonal modulation makes Gwynne's performance  so convincing.  This wonderful, cleverly conceived and  well spun,  life-affirming love  story in particular was the perfect vehicle for his unique talent.  That  Gate-27 was one of the few tales in this great series where horror, fear or blood was not shed makes it all the more enjoyable and rich.
