Did a quick check of my on-hand radio book, John Dunning's On the Air, the Encyclopedia of Old-Time Radio, for the other credited names from Colossus. Nothing turned up, despite my high hopes of finding Reinsberg, the writer (?) on the Colossus feature.
archive.org hosts lots of great old-time radio for anyone who's interested. The OTRR sets, which can be downloaded with extras in CD-sized bites or streamed from single-episode pages, are pretty great: the scifi/horror series available FOR FREE include The Whistler (Biro, Gaines and Feldstein listened to this one for sure!), Arch Oboler, Inner Sanctum, Suspense, Escape, the later Dimension X/X-Minus One...Theater Five (from the still-later early 60s).
Mysterious Traveler, better known to comics folks because of its Ditko print incarnation, began on the radio.
Dragnet and Gunsmoke, from the 50s, are far superior to the better-known TV versions and among the best OTR.
The OTRR group has yet to tackle some classics (or have had their efforts copyright-challenged dubiously by commercial repackagers): the previously recommended Vic & Sade and Lum & Abner (also search the Pine Ridge Project for more eps), Fibber McGee & Molly and Jack Benny (more a show about nothing -- or itself -- than Seinfeld ever was) require some acceptance of loud studio audiences and weekly musical numbers but are still hilarious, Bob & Ray, and the odd works of Ernest Chappell (Quiet Please), Jack Webb as Pat Novak (Webb's first success was a very sly parody of the hardboiled genre), and Carlton E. Morse, whose great I Love A Mystery is only available in pieces (or in its Morse-scripted imitation, Adventures by Morse -- those 60s audio satirists, the Firesign Theatre, had to be Morse fans).
Internet radio station Antioch ABN Old-Time Radio at
http://radio.macinmind.com/ streams an interesting sampling of many of these recommendations and seems to be available through some of the specialty streaming apps on wireless devices.
Enjoy!
