hello I'm just visiting here and wanted to ask a quick question about a name in the song Follow Me Up To Carlow and the general history of the song itself.

The chorus is this: " Curse and swear Lord Kildare/Feich will do what Feich will dare/Now Prince William have a care/Fallen is your star-lo/Up with halberd out with sword/On we'll go for by the Lord/Feich McCool (McCuill? not sure how it is spelled in Gaelic) has given his word/Follow Me Up To Carlow "

Who is Feich? Is it a variation on the name Fionn McCool of the Fianna or is this a different person? And what's the history behind the song?

Thank you :)
