I've never heard the song, so I'm only going on the phonetic version, but I think caught some of it. This is just a "best guess tho'. No guarantees.

De ye leeve bar teese cara - bra, = Dia libh beirt, cara brach = God with you both, good friends Boch-may har-nash har bor-am tra, = XXXX-XXX arnais thar bar an tra = XXXX-XXX back over the beach?? *doubtful* Gan-may-ef san-ha sas-ta harn yav, =XXX-XXX-XX sona sasta ar neamh = XXX-XXX-XX happy and contented in heaven

XXX means I have no idea.

Hope someone who knows the song can assist! Eddie :o)
