Absolutely!
This book is as much a gem as the Opies' book. I remember reading avidly the Opies' book 'The Lore and Language of School Children' as a child and often think that may have influenced my eventual passage into folk song study. It definitely inspired me to note down all of my own games and rhymes and eventually my own family songs and those of the surrounding community.

Before you ask, yes, this is the same Steve Roud of the Roud Index, often quoted in this forum.
