Rock and Roll

Mattias decided to give a rock and roll concert to us.  He set up a stage and a seating area.  He used a vacuum as an amp and a push toy as a guitar.  He was singing and when he finished a song he would put his hand up and say "Thank you".  Where did he get this?  This kid is a sponge.

I tried dragging the shutter to get some motion, I have to work on that.  ;-)
