Bagpipes are an instrument common to both cultures, along with many other cultures throughout history.
Pipe bands, and a lot of punk/rock bands like Real MacKenzies and Dropkick Murphys, use the Great Highland Bagpipes, which are primarily Scottish. They so bear a resemblance to the Great Irish War Pipes, which are pretty rare these days. Both instruments have a limited range (only nine notes), and are usually in an odd pitch (roughly equivalent to B flat, but not perfectly so). They are also very loud, and don't blend well with other instruments, except drums (and heavily distorted electric guitars!).
The more common Irish bagpipes, which we have in my band, and which are played on some of the Pogues' songs, are the
uilleann pipes. They are usually in the key of D, so they are easier to play along with other instruments, and they are at a more reasonable volume. Sometimes they can be in a different pitch, I know "Body of an American" seems to include a set of C natural pipes (at least according to my piper!). Plus, uilleann pipes have a two octave range, and are very versatile. They also sound beautiful in the right hands.
So, playing the Scottish pipes is not completely out of joint with the kind of music that DKM is playing, especially given the sound they are going for:
LOUD, FAST, and OBNOXIOUS! (p.s. they are one of my favorite punk bands, so those are terms of endearment!)
