Edward Woodward's death brings this fine film back to mind. It has much folk content, in the songs, dances, customs, superstitions &c that run as a sort of leitmotiv thru it. One I haven't seen mentioned in any of the notes on it in Wiki, film guides, &c, is the effectiveness of the tune of 'Willie o Winsbury' played on brass instruments as a march at the beginning of the parade which leads up to the final climax.

Any other examples of overlooked folk motifs in it?
