Nigh on twenty years ago I supplied Malcolm Douglas with the Cornish version of Limady, a variant of "Sweet Lemony", used by The Albion Band as the leadout on the stage version of Lark Rise to Candleford.
Although there's a certain amount of debate about the provenance, the source correctly located Morton Nance' previously lost private papers, and the practical outcome is that it seems to have re-entered the Cornish repertoire anyhow, so yr'tis.
