Lenny Bruce - Thank You, Mask Man (1971)

(video link)

Many years ago, I had this on one of those weird home-made video tapes that shows up from who-knows-where.

An animated adaptation of Lenny Bruce's Lone Ranger routine, Thank You, Mask Man was created by John Magnuson, who also directed "The Lenny Bruce Performance Film". This version is featured as a bonus clip on the DVD. I don't know much about the production other than it was posthumous (obviously), and that Bruce was given writing and directing credits.
