Frank Sinatra was an American singer and member of the Rat Pack.
In the Timeless Universe
On September 21, 1962, Sinatra was performing with other members of the Rat Pack, including Sammy Davis Jr. and Dean Martin, at the Sands Hotel and Casino in Las Vegas. Notable audience members include President John F. Kennedy and mob boss Sam Giancana. As the Rat Pack performs the songs "Come Fly with Me", "Ain't That a Kick in the Head", and "Luck Be a Lady", Rufus Carlin, Lucy Preston, and Wyatt Logan are disguised in the audience as waiters looking for Garcia Flynn.
