They were having a great time at show 2 because their families were there right in front of me. I couldn't help to think how cool it must be to watch your dads rock out onstage. Bono's son Elijah kept the beat just like dad did back in the Red Rock days....that was a dead giveaway plus he looks just like him. Edge's son Levi was into it also....so cool to see the whole family enjoying being together.
