They weren’t the original bad boys of stage and screen, but they were the most famous: Frank Sinatra, Dean Martin, Sammy Davis Jr., Joey Bishop, Peter Lawford and so many hangers-on and wannabes, male and female. Revisit the ’60s in this reissue of a classic LIFE special edition—the Rat Pack is in town. Among the highlights:

• A new introduction, commemorating what would have been Dean Martin’s 100th birthday
• Inside the friendship between Sinatra and John F. Kennedy Jr.
• The birth of Vegas and how Sin City became the sensation it is today
• Rare and intimate photos from the great LIFE magazine photographer John Dominis
