Dressed to the nines, Morrison put on quite a show for the music video (in the style of the timeless song) alongside 16 of the best swing dancers in the United States.

"It's some pretty intense stuff," said Morrison of the many fancy tricks he'd been practicing all week. "I'm the novice, so sorry in advance if I kill anyone."
