Mick, did you mean Yankee Doodle Dandy when you typed YDD? If so, they are two different songs: Yankee Doodle is the one that goes "Yankee Doodle went to town riding on a pony, put a ferather in hic and called it maccaroni" etc. and YDD is "I'm a Yankee Doodle Dandy, Yankee Doodle do or die" a la Jimmy Cagney.
