Honestly, Crowley had no idea how to dance to this. He barely knew how to dance unless reasonably drunk and surrounded by hot bodies and a deafening beat. However, this was a repressed gay boy who just wanted to be held. Dance with another boy. So he took his hand and pulled him close, wrapped an arm around him and moved, at least vaguely, to the music, while looking down at Aziraphale.

Good old fashioned lover boy seemed about right for this.
