Spaw,I never saw the movie, but to carry on the connection...
The Rosalie Sorrels album for which Hunter Thompson wrote the liner notes was "Travelin' Lady."
The album on which Rosalie recorded the Sylvia Tyson song was "Travelin' Lady Rides Again."
The liner notes for "Travelin' Lady Rides Again" were written by Oscar Zeta Acosta.
Oscar Zeta Acosta (aka the Brown Buffalo) was Hunter Thompson's "attorney."
Why I know all that is another story.
