Vegas' Best: Sinatra, Cher, Elvis

It's not unusual to see Tom Jones in Las Vegas. The singer is as mentally linked to Sin City as he is to half-unbuttoned shirts and that tan face. Here, he performs onstage at the VH1 "Divas" Concert at the MGM Grand April 18, 2004. Jones is slated to continue playing the MGM Grand through the end of this year. (Kevin Winter/Getty Images)
