The Rat Pack was a close-knit group of Las Vegas entertainers who frequently performed together onstage and in films in the 1960s. They became notorious for their wild carousing, bonhomie, and coolness and acquired a legendary status in their own time that continues to fascinate fans decades after the group’s heyday. Members of the Rat Pack included Frank Sinatra, Dean Martin, Sammy Davis, Jr., Peter Lawford, and Joey Bishop.
