This is a wonderful documentary that came out in the early 90's. If you have seen it then you know what I mean or if you know where to get a copy, watch it.
About a HillBilly tap dancer from Boone county, West Virginia. There are actually two documentaries that are both good
Dancing Outlaw: The Jesco White Story
Dancing Outlaw II: Jesco goes to Hollywood
The latter is about Jesco's short lived appearance on the hit show Roseanne. (Which never made it to the air as explained in the film.)
