I have volunteered to do some nursery rhymes at dd2's nursery on the piano. Can anyone recommend a book of sheet music for nursery rhymes/children's songs? At an intermediate level - so not super simple, a bit more rich with the harmony than the 2 notes right + 1-2 notes in the left hand that I've seen in what I can find online and in the "look inside" thing for one or two on amazon ... I don't know the UK grade system too well but I'm thinking grade 4-6ish would probably be right for me to learn quickly enough, but be more satisfying than the simpler versions. Thanks!
