"Are you sure this is the right note?"

On Sunday, Andy took it into his head that he was going to learn the piano.

Giving him the benefit of my immense musical knowledge, I've been teaching him one of the timeless classics: Baa Baa Black Sheep, it's called. In case you haven't heard it, it's a jaunty little number in the key of C, full of drama, pathos and - remarkably - a kind of bleak joy.

I think he's picked up the tune amazingly quickly. However, displaying his trademark lack of patience, Andy's convinced he'll never learn how to play. With an artistic temperament like that, he surely can't fail.
