St Patrick's Day isn't just a one day thing, in fact the Irish celebration seems to carry on for a week sometimes, so to acknowledge that, here's my favorite Irish song (bet you'll want to sing along - it's very strong and powerful!)
And another version by Celtic Thunder (which I like much better)
And if you really want to get in the mood with Irish Drinking songs, listen to The Spicy McHaggis Jig by the Dropkick Murphys.
And to really get you started on the day, learn how to speak Irish! Read this!
Happy St. Patrick's Day
