And the Corrs' jig might well be "The Rakes of Kildare" or it might be just different enough to have another title. Or it may just be their version of it.
I agree it's not quite the usual form. I used to play "the "Rakes,"" but this time I couldn't recognize it !
When "The Limerick Rake" is played as a jig, it sounds a lot like "The Rakes of Kildare." I believe Natalie MacMaster recorded it long ago, I think without a title.
