Some of the Guiding Light's cast...
...will be appearing here in a live show. It's called "So long Springfield" and it's a day long event - if you want to buy all three parts of it. OR you can just buy the daytime show or the evening show separately, with or without the brunch with the cast. Go here and scroll down a little:

It must be just the cast who is not working elsewhere yet. Wonder if this show is elsewhere also.
Edited to add - I did a google search of "so long Springfield" and it is, indeed, going all over the country. If you're interested, look to see if there's one near you.
