You can see in the 1st two photos that Avery is not completely pleased with Sandi's interpretation of the music and she tries to correct her but quickly abandons her to 'go change the music', maybe that will help.
On the last couple of nights we discovered a stage where there was some music playing. It then became our nightly ritual to go and have a 'dance party'. This means Avery dances, pretends to frequently change her earrings, shoes, dress, hairband and then lets you know if you are allowed to come and dance on the stage with her. Once you are on stage you then have to follow all of her detailed instructions. I know I am going to have trouble editing down the photos so settle in to enjoy the show...
You are not seeing things, that is Muddy sucking on Auntie Marg's toes. Avery puts her face in up to her lower lip so she can blow bubbles. She is a real daredevil.
