Nice alternative came up in conversation last night - Horkey. Definitely an English word, an East Anglian term for a harvest celebration, but the content of the event is very similar - general party with music, dance and song, though the accounts I've found don't exactly match a modern so-called ceilidh. Looks fun though...

See The Brook Hall Harvest Horkey,
Little Egypt Horkey Gear and links from the latter, especially Horkey99

Anahata
(wondering whether to start advertising a "horkey band" and see what happens.
