Oh, bad news, this site seems to be down now. At least it has been for the past few days.
The site seems to be working fine today. (Saturday) :? I have noticed there are times when it won't load, usually after school or on weekends when lots of kids get on the internet. Maybe they overload the server or something. If you can't get in at all I find it helpful to save the URL of one of the actual lists of tracks in my bookmarks and you can sometimes bypass whatever isn't working. What I run into most in the high traffic times is that it will load the list of names but will take forever to load the "play", "pause", and "stop" buttons. (And I mean forever. Once I left it alone for three hours and It had only gotten down about a third of the page.) Hope this helps. If you want to go straight to some of the episodes try
http://oldtimeradio.homeip.net/otr/superman4/. If that won't load in about 10 minutes try again at 10:00 AM in the morning.
PS. Thanks for the other site. I'll see what is says.
