Several clips from a 1953 filming of the Padstow, Cornwall, May Day “hobby horse” procession are available on the Web. The film was made by Peter Kennedy, George Pickow, and Alan Lomax, an American folklorist.

Some .wmv selections are here.

But the best clip is here, especially for its slightly eerie, archetypal ending, which some people say prefigures The Seventh Seal. UPDATE: This last link no longer works.
