Tom Glazer has found in his work with children that they are "intensely delighted in participating in my concerts right in their seats - not only by singing along, but by acting out songs in various ways...it has become quite clear that almost all healthy children have a deep need for dramatic expressions, even on primitive levels, which requires the merest encouragement to come out."
This book has the music and lyrics for lots of old children's tunes, plus instructions for doing fingerplays with most of them. I knew most of the songs already (BINGO, This Old Man, Where is Thumbkin).
