FWIW, The Doo-Wop Express is now streaming online, 24-7. This is good news for me, as the local ingrates decided to drop its Saturday night slot for 'local country'. Good lord.

It's syndicated over regular airwaves too, but I can never seem to catch it. Needless to say, it sounds even better over a proper vintage radio...
Thanks for the info on 740 AM Dan, good post-
