During the late 1950s and early 1960s, a group of little gods such as Dean Martin, Sammy Davis Jr., Peter Lawford and Joey Bishop in sleek suits reigned over a magical playground called Las Vegas. These hedonists belonged to the Rat Pack and their king was Frank Sinatra who had turned into that cool insolent crooner after his separation from Ava Gardner. The ultimate old boys club, it was nonetheless a woman who found the legendary name. The Las Vegas tribe was indeed preceded by a group of Hollywood pals centered on Humphrey Bogart and Lauren Bacall who liked to entertain their friends such as David Niven, Frank Sinatra and Judy Garland in their Beverly Hills home. One night, Lauren Bacall looked upon her friends and said ‘You look like a pack of rats.’: a name that stayed although Frank Sinatra who became the leader of the clan at Humphrey Bogart’s death in 1957, disliked it. These guys made films together such as Ocean’s Eleven, preformed together at the Sands hotel, exchanged girlfriends and even campaigned together for a president as Frank Sinatra served as the charismatic link between the mafia, Hollywood and the Kennedys. From time to time famous women entered the pack, such as Shirley MacLaine or Marilyn Monroe who dated Frank Sinatra. But alongside the Rat Pack, Frank Sinatra also had his own family tribe and led a special relationship with his daughter Nancy who perfectly made the transition from the elegant vocalizations of her father to provocative tunes with These Boots are Made for Walkin, installing the name Sinatra in pop.
