There is another verse which is sometimes sung at the end:

Go hUíbh Ráthach má théann tú beir scéal go dtí mo mhuintir
go bhfuilim daor ar an bhfód seo is nach bhfuil beo agam ach go hAoine.
Bailigh gléas tórraimh agus cónrá breá im thimpeall.
Sin críoch le Ó Dónaill is go deo bí ag guí orm/liom.

(If you go to Ivereagh, bring the news to my parents, that I'm condemned on this sod and I will not survive past Friday.
Gather the things for my wake and a fine coffin around me
That's the end of O'Donnell, and beforever praying for me/with him
