Just to confirm what Mick said above - those are the words I always associated with the tune.

Packie was also born in a Donegal cottage with a half door - no longer standing, alas, but I remember seeing the remains of it years ago as a cattle-byre. Now even that is gone. He used to talk about people dancing on the half-door, plaiting St Brigid rush-crosses (I have one he made for me) and other customs likewise gone forever. He said (as Big Tim has already mentioned) the door was for "keeping the animals out and letting the fresh air in".
