I always said, I made a bunch of money playing tunes , some Irish, like "Irish the brave"(one day only) most Scottish and some merican on a set of Great HIGHLAND Pipes, dressed in a British army uniform for a bunch of wanna be Irish, on an Welsh Catholic Saints Feast Day. also I get free beer and whiskey

on topic, I have also been told the reason is the Irish association with Fire and Police Departments, which also explains the prevalence of Pipebands sponsored by said organizations
