Here are lyrics for Follow Me Up to Carlow. I don't believe The Swallowtail has lyrics.

8. Follow Me Up to Carlow (Patrick J. McCall)/The Swallowtail (trad.) 3:36
Big Mick (The Conklin Ceili Band)
(This song recounts the Battle of Glenmalure that occurred on the 25th of August 1580, in County Wicklow. Tom Verlin, who plays mandolin on this version, came up with the idea of using "The Swallowtail" for the break and to end the song. The fit was a natural.)

Lift Mac Cahir Oge your face, brooding o'er the old disgrace
That black Fitzwilliam stormed your place and drove you to the fern.
Grey said victory was sure, soon the firebrand he'd secure
Til he met at Glenmalure with Fiach Mac Hugh O'Byrne

Chorus: Curse and swear, Lord Kildare, Fiach will do what Fiach will dare
Now Fitzwilliam have a care, fallen is your star low.
Up with halberd, out with sword, on we go for by the lord.
Fiach Mac Hugh has given his word, follow me up to Carlow.

See the swords of Glen Imall, a flashing o'er the English pale,
See all the children of the Gael beneath O'Byrne's banner.
Rooster of a fighting stock would yet let a Saxon cock,
Crow out upon an Irish rock, fly up and teach him manners.

Chorus

Now from Saggart to Clonmore, flows a stream of Saxon gore,
And great is Rory Oge O'More at sending loons to Hades,
White is sick and Grey is fled, now for black Fitzwilliam's head,
We'll send it over dripping red, to Liza and her ladies.

Chorus
