Constantweeder was born in Los Angeles in February 1934 and attended many radio broadcasts in nearby Hollywood beginning in 1943 with the Jimmy Durante-Garry Moore show at NBC Radio City, and later attended such shows as Fibber McGee and Molly, Meet Corliss Archer, Sherlock Holmes, and the Jack Kirkwood Show. As a faithful radio listener, he learned to identify actors and announcers by the sound of their voices. Even today, when used as background noise in movies, he can spot them; example: the closing scenes of "The Day of the Locust" (1975) uses the recorded voice of NBC Commentator H. V. Kaltenborn describing the terrible events in Nazi Germany in 1938, when the horror of Kristalnacht paralleled the action shown in the film. Radio faded away with the arrival of television. Constantweeder met Bob and Ray in Radio City New York in 1949, and had lunch with Sandra Gould (Miss Duffy) at the Brown Derby. As a child he wanted to become a radio announcer.

The first hundred or so contributions by Constantweeder were from memory and did not rely on published sources; however, they are accurate. His favorite show was Vic and Sade, which he still hears in his memory.
