Book excerpt: Tap dancing on sidewalks, especially in the city's French Quarter, is a New Orleans tradition as familiar to some as Jazz, Creole and Cajun food and Mardi Gras. For generations, Black youngsters have danced for tourists on the streets of New Orleans some because they enjoy it, but many others to earn money for their families. Instead of dancing in store bought tap shoes, young boys and girls stamp and grind bottle caps into the soles of their sneakers until the bottle caps stay firmly in place at the toe. And they don't miss a beat! Clickity-clack, Clack......tipity-tap, tap tap......tipity-tap, tap In Bottle Cap Boys Dancing on Royal Street, award-winning author Rita Williams-Garcia introduces two bottle cap dancers, brothers Randy and Rudy. Through rich and upbeat rhyme, Williams-Garcia gives voice to the dancing and the youngsters who keep this unique New Orleans tradition alive. Damian Ward's exuberant illustrations are perfect complements to Williams Garcia s perfectly pitched poetry.
