At the morning assembly at Rockwell Elementary this spring, the music teacher, Mr. Meyer, led everyone in some songs. On a whim, I asked him if he wanted to join me and play some improvised accompaniment as I read Bean Thirteen. We had so much fun that he came back and played along as I presented several other books throughout the day. (The plan is for us to tour together next year, if I can convince him to quit his day job.)
