SNAP! BOMP! BEEDLE-DI-BOP! In this toe-tapping jazz tribute, the traditional "This Old Man" gets a swinging makeover, and some of the era's best musicians take center stage. The tuneful text and vibrant illustrations bop, slide, and shimmy across the page as Satchmo plays one, Bojangles plays two . . . right on down the line to Charles Mingus, who plays nine, plucking strings that sound "divine."
