Duffy, O Máximo de Vigarice

Wondering if there were ever any copies (videos or DVDs) made of this movie. It's a small classic of a not very widely exploited genre (a certain hippie lifestyle which in the U.S. was captured in Easy Rider but which does not have many European counterparts -- though this film is much lighter and more comedic than Easy Rider). By the way, the beach club in the film was a specially constructed set, demolished after the filming was over. I know cause I was an extra in the scenes shot at that location. The location itself was a beautiful uninhabited spot on the coast about an hour's drive across mountains and desert terrain outside of Almeria, where the rocky, pockmarked cliffs dropped straight into the sea. If anyone could tell me whether it might be possible to obtain a copy of the film -- have searched all known sources without success -- would greatly appreciate it. James Coburn fans in particular would love this film which I think would be greatly enjoyed if run again on T.V. or released in video/DVD format.
