Although this "short" is very hard to find - you are most likely going to have to hunt for a bootleg copy somewhere - it is worth the hunt for anyone who understands the historical context of the picture. It was the only film the beats ever made, and the highlights can are to be found in the narration by Jack Kerouac and the musical score (classical / be-bop / jazzy) done by David Amram. The themes are typical of the beats and of Kerouac - railroad brakemen, beer, poetry, pot.. etc, but in all seriousness this is a rare gem and gives a brief look into the consciousness of the beat poets / writers. Kerouac sounds drunk and probably is drunk, but that just adds to the aura and humor of the film.
