While at an American Irish Pub, drinking some what heavily, my friend and I began to discuss the common threads to Irish folk music. We theorized, as much as one can theorize after 4 or 5 pints of cider, that you can place all the songs into one of 3 or 4 categories: Songs where everyone gets drunk, everyone dies, somone goes to America, or any combination of those three for a total of 7 categories.Can anyone do it in less?
