Drew's favorite song is "Un-do It" by Carrie Underwood.  Whenever I play it in the car he gets so excited because he knows the words, "uh uh uh uh uh"  Here he is bopping along to the song while eating his snack.  If you listen carefully, at the end he says "bye-bye Uh Uh" and then "gain" Drew's word for "again"
