Noble Duke of York

Oh, the noble Duke of York 
(gently bounce baby)

He had ten thousand men

He marched them up the hill 
(raise knees up or lift)

And then he marched them down again
(lower legs)

And when they're up, they're up
(raise legs)

And when they're down, they're down
(lower legs)

But when they're only halfway up
(raise legs halfway)

They're neither up nor down
(raise up and down quickly)
