Listening to the radio

I just learned about a great website that I want to let you in on. Radio Lovers has lots of old-time (before my time even!) radio programs, at least some of which might be suitable for ESL/EFL students to listen to. They are available for free and, as nearly as anyone seems to know, without copyright issues. I want to explore these and see if I can't find a way to use some of them to spice up my classes a little. If you aren't familiar with the site and like old radio, check it out.
