Without missing a beat, September twirls and the music shifts from offbeat 80's to 30's swing, his footwork taking on a classic tapdance cadence.

"Happy feet," he sings, and quite well, I might add....
"I've got those hap-hap-happy feet!
Give them a low-down beat
And they begin dancing!
I've got those ten little tip-tap-tapping toes,
When they hear a tune
I can't control the dancing, dear,
To save my soul!"

He apparently can't control the singing, either, even though his face remains expressionless.
