Stumbled across a website called ZOOTRADIO.COM.
An amazing collection of radio drama ( Ted's in his element ) I've pillaged the music programmes. There are some greyed-out listings on the site which include some absolute gems. I understand they're "repairing" the site. Not sure what happened, but I hope they fix it all soon. Copyright isn't a problem since none of the material was registered for copyright in the late seventies when the U.S. copyright laws changed and there was a "window of opportunity" for radio stations etc to register their old recordings. and so they're considered to be in the public domain. The site also maintains a policy of removing any copyright material as soon as it's brought to their notice.
You have to register, but it's quick and totally free.
Here's the link:
