Head, Shoulders, Knees, and Toes.

I was sitting on the chair when the song came on and so I just reached for my knees and toes while sitting in the chair...

She thought it was a great idea.  Insisted on her own chair... 

Then lays her head on the opposing chair to hold herself up while she reaches her knees and toes.  

Now when the song comes on she hurries to the chair, if someone is sitting makes them move and then continues on... hopefully in time to make the part of the song.
