In the preview I watched a month ago, Annaleigh would fondly touch Jake's arm, back, hair, and beard during her first song (one of the production promo photos shows her touching his beard). This time around, she didn't touch his face at all.)
During "Color and Light", Jake had 2 paintbrushes when I saw it in previews. Tonight, he didn't use any brushes at all but from his hand movements it was obvious that he was pointing the brushes to the canvas like dots.
