Book excerpt: "Square dancing is friendship set to music," says author Betty Casey. Just take four couples, old or young, put 'em on a good floor, turn on the music, and you're all set. Whether you've done it before or you're just starting out, this book tells you everything you need to know--85 basic movements used all over the world, the spirited calls unique to square dancing, the costumes and equipment that are best, and music (from "Red River Valley" to "Mack the Knife") that will set your feet in motion. Down-to-earth details and anecdotes give a taste of the good times in store for you. Find out how native folk dances grew out of European quadrilles, jigs, and fandangos. Open this book and get ready to: "wipe off your tie, pull down your vest, and dance with the one you love best." This book includes: 50 basic movements, 35 advanced movements, variations, dances that are a part of the American heritage, Contra and Round Dances, polkas and reels, and calls, past and present.
