And the siren sounds on 40 years of peace with a nostalgic look at the days when swing was Glenn Miller , jokes were corny and George Formby ruled the Varieties. There will be no rationing of entertainment at the Royal Hall, Harrogate, when the Syd Lawrence Orchestra , Charlie Chester and Alan Randall join forces to re-create the atmosphere of a 40s dance. Presented by Alan Sykes Producer ROGER LUCAS BBC Manchester
