I haven't gotten a copy for myself but I notice that Amazon is selling this 2-CD set called The Greatest Comedy of All Time. It's a bunch of old tracks, mostly from radio shows, of W.C. Fields and Bob Hope and Abbott & Costello and people like that.
You can order a copy here if you like…but me, I'm a little skeptical about this thing. I get the feeling whoever put this together doesn't know that much about great comedians. You see that photo of Groucho on the cover? That's not an old photo of Groucho. It's a new photo of our friend, Groucho impersonator Frank Ferrante.
