Mary Hicks, mother of the late Bill Hicks, is taping an appearance this afternoon on Late Show with David Letterman that will air Friday and include the twelfth and final performance by Hicks that the show had censored back in 1993. Why the change of heart now? We'll find out soon enough. Next month is the 15th anniversary of his early death, with events planned in England (the Brits always loved Hicks) and in Portland, Ore. (where childhood friend/comedian Dwight Slade lives). And later this year, the British-produced documentary American: The Bill Hicks Story should make it to the big screen.

In this segment from an earlier documentary about "Outlaw Comic" Hicks that I recall seeing at the HBO Aspen festival in 2002, Janeane Garofalo says in a voiceover how Mary Hicks received the only existing tape of the set from CBS and the show, but they couldn't use it at the time. Instead, they show part of the final performance ever from Hicks in 1994. Were he alive today, you can imagine how he'd feel about Miley Cyrus…

And in this public access TV appearance, Bill Hicks himself talks at length about his disputed appearance on Letterman:
