This is the documentary by Sara Michener about Bob Pyle: musician, art collector, and otherwise odd and interesting person in Ellicott City, Maryland, US.
We're aware of two other "Bobumentary" documentaries available on the net:
one about Bob Marley (try Bobumentary "Bob Marley") in the search box below),
and one about/by Bob Flanagan (try Bobumentary "Bob Flanagan").
And, of course, there may be others...
