Cragie Hill comes to mind on this. Initially the woman is asking the man not to go to Americay, but the man seems to me to be happy to be escaping ! The third verse runs something like :

"And after a short while, If fortune should prove pleasing

'twill cause us all to smile at our sad going away,

We'll be happy as Queen Victorie, all in her pride and glory,

We'll be drinking wine and porter all in Americay."
