I seem to remember a last verse going something like this:

And if ever I do return again, my own native land to see

It's there my friends will greet me, with a smile dum, dum, dum, dum, dum (sorry I forget)

And my own true love is as dear to me as the flowers that blossom in May

With a "cead mile failte" they'll welcome me back from the shores of America.^^
