Well, my paid St. Pat's gigs are in retirement communities in the US, so my list of possible songs to play includes a lot of the 'Irish songs they want to
hear, e.g.:

How Are Things In Glocca Morra?

Then I have my other list - songs that may be a little less known to my audiences but which I like to sing and from which I always throw in a few:
