The Music by Herb Geller
The only Otto Movie that is mostly enjoyable. And that because of the great cast and also because of the music in my opinion.
Sadly the music did never had a release. May be because it is only like about 20 minutes all in all. Sadly composer and Jazz legend Herb Geller past away in 2013 and there is still no release of the music in sight.
Lately I discovered a version of the main theme on YouTube that was released many years after the movie was released. Enjoy.
