"The Baby's Opera" by Walter Crane contains the music for many English nursery songs, and is one of Crane's best known 'toy books'. Complete with colored illustrations, this book has been a favorite among children since it was first released. Girls and Boys, Baa Baa Black Sheep, There was a Lady Loved a Swine and more nursery rhymes are collected in a single place here with sheet music to allow young students to play along with instruments and stay in tune.
