Regarding the earlier lyrics which Padraic Pearse rewrote and politicised, they've been recorded by Pádraigín Ní Ullacháin. She only had the lyrics, so she composed a tune, very similar to the one used in Pearse's song. sorry, I don't have the lyrics, but Pádraigín includes all lyrics with her CDs, which are worrth purchasing if you're especially interested in songs in Irish. Not a Dubliner-type soound, however.
