Yes it is really a show! I comment on it because I like it. I am ancient gasbag too, but I am still entertained by the program. Some of the guests I don't care for, others are great. The best part for me, is listening to the interplay between the hosts and the callers. I never heard a podcast before where the host will actually interrupt the guest to bring in a caller. I love that!
Also, when I first came here, they reached out to me because I started a Caravan to Midnight thread, and actually had John B. Wells as a guest.
I would go through the programs, see which guests interest you, and start there. If it's not for you, try the Mallard report. "quack"
