'English Country Dances'
a) is a bit of a mouthful
b) sounds odd in an English (especially rural) context, and
c) has connotations of patrician urbanites playing at being peasants.

These days, 'ceilidhs' happen in England, & are mostly jolly (preferable to ECD's!)...Down here, indeed, the word has taken on a life of its own!
Must admit to being uncomfortable with the Gaelic spelling, as I understand the word has a different significance in a Scottish or Irish (esp. Gaelic/Irish-speaking) context, so I tend to write the word 'kaley'.
e.g. 'Wishing I was at a kaley in Chippenham....'
