I have a sentimental fondness for this one. When I was in college in the late 1970s, on the night when a girl I had a crush on told me she had chosen a rival suitor, a sympathetic bartender served me three of these gratis. He called it a Godfather (which according to Simon is made with scotch, not bourbon, but it's the same concoction no matter what you call it). I remember stumbling back to my dorm but not much else.
