Popular!? Yeah, right. I imagine there are conveniently no Arbitron figures to back up this contention. Popular amongst left wing media boobs maybe, but no one else.
------------------Time for research------------------
I looked it up on Google and found this in a press release:
Arbitron estimates that "A Prairie Home Companion" has 4.1 million listeners.
This is probably cumulative, like, over the life of the show.
I have traveled to see his show many times. Always in big halls, and always sold out.
He tells stories about people I love, many now departed but he can bring them back for me. I love his stories, and they are one of the really special things I can share with my normally un-emotional father. Yes, his show is still popular.
