A Singing in bed

I sit with A for a while at bed time. The goal is to help him calm down and go to sleep, but sometimes it doesn't work! We've managed to get to church for a few weeks in a row now, and it has made quite the impression on him. He's fascinated with the conductor and likes to play "conductor and choir" at home. He climbs up into his bed with a straw, a pen or some other kind of "conductor thingie" and has us sing "Thine is the Glory". He's heard it enough that he's got a good grasp of the words. Occasionally, he'll pick up his little bible and start singing once I leave the room. One night, he started in while I was still there. This video was taken in the dark, so there's no picture, but you can clearly pick out the songs he's singing!
