It starts (with a pronounced Yiddish accent):

I'm a Yankee Doodle Dandy
I've got a Yankee Doodle Son (a tramp! a bum!)
He works downtown on Delancy Street
Just like Abe Washington
Last night, he brought me home a paycheck
It was a half a dollar short....

Here an aging memory faileth. Any urban types recall the rest?
