Will an 18-month old watch Sesame Street Live?

I took my daughter to see SSL at 18 months old and she loved it! I couldn't believe how still she sat, it actually held her attention for the entire show. And my daughter is not normally one of those mellow toddlers who likes to sit on mommy & daddy's lap. She is full of energy and normally can never sit still, so it was shocking to see her this way!
