One of the joys is finding an online repository of "Lights Out" radio plays from the late 1930's/early 1940's, flowing through the peak of WWII time. Hearing these plays within that context is fascinating, particularly with the intermissions and advertisements. And on random play, they come up betwixt songs and surprise me. It's rather nice, though now I have a desire for ironized yeast tablets.
I need more Nick Cave and Tom Waits though.
