Do you ever wonder how Vegas used to be? Before Kanye, Kim, Nicki and Taylor? Get a nostalgic look back with the Rat Pack Is Back in the intimate Copa Room at The Tuscany Suites & Casino. Get started with a little Rat Pack trivia and photos of vintage Vegas to get you in the mood to help celebrate Frank Sinatra’s birthday—Dean Martin and Sammy Davis Jr. might just stop in to help.

With the seven-piece Lon Bronson Band providing excellent music, Frank (David DeCosta), Dean (Drew Anthony) and (Kyle Diamond) each belt out classic tunes such as “Luck Be a Lady,” “Fly Me to the Moon,” “That’s Amore,” “Volare,” “That Old Black Magic” and “The Candy Man.” In between are plenty of jokes a la the original Rat Pack and audience interaction, with the guys schmoozing the ladies, drinking up the crowd’s drinks, making toasts and ribbing one other.

The entertainers look similar to the real thing, channeling Rat Pack’s voices and mannerisms. They all dress in period-appropriate togs, with Sammy being the most dapper of all, except perhaps when Dean and Sammy have a little surprise for Frank’s birthday, appearing in outlandish costumes. Those type of skits lead into song, such as when Dean pulls out a long, long piece of music and persuades Sammy to play along.

They all get together in the end for a few last numbers, leaving the audience with a sense of the fun and fellowship that the Rat Pack brought to themselves and their fans.
