John Marchini was raised in Northern Ireland. He currently works for the counseling department of the New York State Fire Department. The term "black and tan" refers to the Royal Irish Constabulary Reserve Force sent into Ireland by the British. A black and tan drink is half Guinness (top) and half ale (bottom). To pour it at home, pour over a spoon.
John will be marching in the St. Patrick's Day Parade in New York this March 17.
