Review of David Letterman's Holiday Film Festival

I wish this was out on video because it was one of the most hilarious shows ever to be broadcast. My sister and I still quote from "PMS" - the Andrea Martin/Catherine O'Hara short. The weak points are David Letterman's short and Bette Midler's "Why Bother?". Of course, even the weak points are great. The musical number in the industrial parody is also great. A musical production number about "Farm Implements!" Brilliant! The 1986 special is available but NO ONE - and I mean, NOBODY - appears to have this rare 1985 bit of brilliance. I've looked in broadcasting museum collections. I've checked message boards and collectors on Ebay. No luck. If anyone ever knows how to get a copy - please post it here!
