Trying to explain

Today we were all hanging out at a craft show. Wesley was trying to explain something to us and we couldn't understand him. He kept saying "tong, tong, you know la la la la" then we finally got what he was trying to say. Song! There was a choir practicing that he could hear. Also on the way home the radio was on and a song came on and before they even sang anything only a few measures into the music he yells "favorite song, jump!" he then starts dancing like crazy in his car seat and yelling "jump, jump, jump around get up get down". The crazy thing is he has only heard that song a few times!
