I take it we are talking of the tune which originally belonged to False Foudrage but became associated with Winsbury because someone [one of Planxty IIRC] once got confused in looking it up?

Yes - on checking, I find a reference to Andy Irvine having claimed to unconsciously slipping into the Fause Foodrage tune while doing Willie Of Winsbury so it became universally assoc'd with the latter.

I take it that is the tune we are addressing in this thread?
