Everything worked in my days as a Beaver leader. Those 5 to 7 year olds were willing to sing anything. I found Cub-aged kids to be tougher to please but you could still pick tunes out ot the standard boy scout song books - Start with "Mctavish is Dead" and get progressively gruesome from there. My last three years as a Scout leader wer frustrating from a musical perspective. I, a child of the 50's and 60's, found it difficult to compete with commercial radio. If you can't beat 'em, join 'em. I started to do rock & roll music. "Paint It Black" caught their attention. So did the Beatles' version of "My Bonnie Lies Over the Ocean" played it with a fast Chuck Berry rhythm.
