A friend of mine found this book at Value Village.
It is, as you may be able to tell, a disco instruction manual. The book's heroine is Dopey Debbie, a young woman "in the prime of her dancing and dating life," who for some reason spends all her time at home playing Old Maid with her best friend, Grotesque Gertie - or sometimes, even worse, watching black-and-white TV. The horror!
Author Roy Madrid (winner of both the Disco Dance Instructor of the Year Award and Top Disco Couple Dance Award at the 1978 Dance Rock Awards) encourages readers to practice beat counting all the time - even "while giving a home permanent."
Evidently Debbie has done both of these things.
Work it, girl! Love the shoes!
