I heard this Scottish rock song what was it called?

I think it was Scottish but anyway it started off with like a bag pipe and drums.. the drums went DUNN DUNN and then the bagpipe played and then the drums do DUN DUN while the bagpipe is still playing... then a guy said something like this "We'll FIGHT THE BLABLABLA AND BLABLABLA" it was pretty good... any ideas of what the song was called? (heard it in an amusement park) Sorry for being vague thats all i remember... i couldn't really understand the lyrics..
