At junior school we used to dance long morris to 'Yankee Dandy' and sang the chorus as

'Yankee Doodle KICK it up'

Kicking twice, alternate feet on kick and up, and on the last line doing two large circles with the hands.

I am not sure that the last two lines are what we sang though - it is over 50 years ago now and my memory is not what it was.

I think that the third line also began with Yankee doodle.
