The 'buzzing' sample in House of Pain's Jump Around

Whenever I hear the song Jump Around I think about the obnoxious buzzing sound that accompanies the song, and despite everyone finding out where the beat and the sax/scream came from nobody talks about this particular sample that is pretty much there the entire song. I don't think it helps that in newer copies they remove the sample altogether and it just doesn't feel right, but you can find the version playing on radio (and older copies on the net) having this noise. Is this even a sample or am I going crazy? I don't think it's an error because everything else in the "newer" version sounds identical to the "older" version, and the buzzing appears to possibly be intentional. I believe these buzzing sounds come from bagpipes considering the group's Irish heritage.

I wish I had a better way to describe this but I'm trying as best as I can.
