Information for Rat Pack Live at Devonshire Park Theatre, Eastbourne (Concert). It's the ultimate tribute to legendary Fifties and Sixties phenomenon the Rat Pack - Frank Sinatra, Dean Martin and Sammy Davis Jnr. They were the definition of cool during their Vegas heyday, combining the full sound of big band swing with charisma, panache and swagger. This unique chapter of musical history is superbly recreated by the original Rat Pack Live concert show. Congress Theatre
