I can understand about OTR comedies not appealing to everyone. Based on what we're used to seeing/hearing as comedy nowadays, I usually stay away from the OTR comedies because, while they are amusing at times, I can't give them the belly laugh that others do. HOWEVER, I have found Fibber McGee & Molly to be quite humorous! I can't listen all the time, but the little I've heard, I have enjoyed. I've caught a few other comedies on the Sirius OTR channel, and they are OK. I'll listen, but a lot of times they come across as silly to me instead of funny.
I've heard a little bit of Gildy, but it just really wasn't for me. I like Eve Arden, but I can't take too much of Walter on Our Miss Brooks (I prefer him as Col Trautman). I've heard others, but nothing that made me laugh like McGee & Molly.
