I'm sold. I watched "Hootenanny" in my teen years. My favorite little-known "Hootenanny" fact: The theme song lyrics--"We'll have a hootenanny, hootenanny Saturday night..."--were written by a fairly young Alfred Uhry. He won the Pulitzer Prize. Not for "Hotennany" but for "Driving Miss Daisy."
I interviewed Uhry a few years ago and we had the devil's own time trying to recall the second line of the theme song. Finally, he came up with it: "We'll raise the roof and the rafters with song."
