Its fleece was white as snow

D and J have started piano lessons. The teacher is very good, and speaks English quite well. Last night, she brought with her a couple of music books for beginners - in Chinese, but I suppose that doesn't matter, the music is the same, whatever the language. "You know this note", she said to D, opening the first book (when she says note, she means song, but luckily they've both realised that now and make suitable allowances) - "You know this note. It is Mary had a Sheep".
