Bill Hicks on The Late Show with David Letterman
Back in October 1993, comedian and gadfly Bill Hicks performed for the taping of Late Show with David Letterman. However, his performance was famously cut from the airing of the episode that night and never saw the light of day. Hicks, unfortunately, died of pancreatic cancer just months later. Last night, more than 15 years later, the show invited Hicks's mother to the show as it broadcast the clip for the first time.
