Here are all of the children walking in. It was just the two 4yr old classes, so about 30 children total.

In this picture the children have just sat down and are looking in the crowd to find their parents. On the video you can see that Lucas is looking around with the expression below, and then when he sees me his face lights up with a big smile : ) A few minutes later he spots Jeff in the balcony and smiles again as he points to him and motions to me to look too. Lucas is sitting beside Addison and Patrick.
