Patrick Alfred Muldoon
Fictional Scottish bagpiper with "big fat floppy jowls" from the Ray Stevens novelty song "Bagpipes (That's My Bag)," off his 1969 Gitarzan album. The track was also reused on his 1974 Boogity Boogity album.
The song doesn't actually have any bagpipes on it, but it does have Stevens imitating them with his voice.
The song descibes Muldoon coming to the U.S. from Scotland, starting a rock and roll band, and playing "up at Harvard and down in Vanderbilt."
