Ceili Rain-look for either greatest hits or Erasers on Pencils. Thier more on the Christian music side of things but still very celtic and very upbeat. if you are looking for something with a bit more rock and roll to it I'd go with Barleyjuice, the Pogues, Young Dubliners, or Great Big Sea who have alot of good songs.
