In order to get the blood roiling enough to make you want to pick a fight with and Englishman then have a pint after, you really should listen to or better yet watch Albannach. They're a "tribal" group out of Scotland that usually make the Highland Games tours during the summer. Their latest album Eye of the Storm I thought was their best yet. They have a version of The Gael that just makes you want to knock someone out. I use it when I'm working out.
