My sister reminded me that the "Chateau" was on Clark st. not far from the Aragon Balloom. It was very popular as well. In the mid 30's Eddy Howard was the big band there. She also knew people in the "21 Club" and took dance lessons from some of them The 'Club' at the Chateau was called "The Regulars" I ordered the "Dream When Your feeling Blue" book from Amazon for each of us. Thanks so much for the information. dorothy
