Okay first of all, if you are a "Man of Steel Marathon" fan a new Superman storyline is running over the weekend. It begins Friday at 8pm ET 7 CT then on late Saturday night for all of you West Coast folks (or really late night East Coasters) it will air at 11pm Pacific Time (2am ET) - then again on Sunday morning 8am ET and finally on Monday Labor Day at 2pm ET (11am PT). After the 90 minute special I have added a "new" episode of The Chase.

Okay a new schedule is ready for the first week of September and it is attached right here in Excel format.
RadioClassics Grid 2008-09-01 Wk-Landscape.xls (28.50 kb)
Highlights include a Lux Radio Version of Winchester '73, "new' episodes from Alan Young, Frank Race, The Chase, Richard Diamond, This Is Your FBI, Suspense, Inner Sanctum, Mysterious Traveler, etc.
You might really enjoy yet another new show known as Behind The Mike. Just like it sounds you'll learn about actors, sound effects, transcription vs recording and much more from this program that first aired back in 1940.
