Rossa's Farewell to Erin has a version in the DT and the tune is given as the Boys of Wexford. (Colm O Lochlainn in Irish Street Ballads describes his version of the tune there as "a poor version of The Boys of Wexford" - but it'll sing well enough to either tune.)

(Incidentally O Lochlainn gives a different set of names for the traitors - Nagle, Massey, Corydon and Talbot, instead of the DT's Nagle, Noone, O'Brien and Power.)
