Watching Bob Anderson perform as Frank Sinatra on the Las Vegas strip might be as close to it gets to seeing “Ol’ Blue Eyes” live.

Anderson, a famous impressionist, performs a few nights a week with a 32-piece orchestra in “Frank: The Man. The Music.” at the Palazzo Casino Hotel.

“You’re Frank Sinatra baby,” Anderson jokes to himself to get in character just before going on stage.

Anderson’s complete prep for the show starts with 90 minutes of make up designed by Hollywood master artist, Kazu Tsuji—the man who transformed Brad Pitt in "Benjamin Button."

The Emmy Award winning makeup artist applies Anderson’s blue contacts, aging make up, and a prosthetic nose. The Sinatra transformation is so complete you feel like you're looking at the real deal.

After make up, Anderson heads to his dressing room, where he neatly organizes his “must haves.”

He avoids “Vegas throat” by using a humidifier and an insider trick: local desert honey that fends of pollen.

“The entertainers know about it,” Anderson said.

Anderson then picks his outfit. He chooses from one of four crisp white shirts that hang with accompanying shoes and ties.  

If he gets hungry he turns to an Italian staple.

“The pizza,” Anderson joked.

He loosens up with a drink of whiskey and walks down the long hall warming up to Sinatra tunes coming from his cell phone.

Then, it’s show time.

But, Anderson isn’t just talented. He has a special connection to the bygone era of Vegas.

“I just caught the tail end,” Anderson told Fox News “I was the last guy to ever catch the golden age of the strip.”

Anderson was friends with old Hollywood stars including members of the Rat Pack,  Johnny Carson and Merv Griffin. He recalls a star-studded party at griffin’s house that changed his life.

“Carey Grant was sitting on the floor with his back up against the wall and I remember him saying ‘Boy this is really something I’ve never seen anything like this, this is amazing.’ And I’m looking down oh that’s Carey Grant sitting there,” Anderson said.

Anderson did his impressions for the crowd on Griffin’s piano and the rest is history.

“He said we found your act,” Anderson said. “You’re going to be the singing impressionist."

Anderson has stared in other shows including one at the Legendary Dunes. But he says this show he's headlining is special because it's an ode to Sinatra’s era. He hopes it shows younger generations what it felt like to be at a classic Vegas show.

“Come back and sit for an hour and a half and see what the entertainment business was like,” Anderson said. “The subject matter is the most famous entertainer that ever walked on the earth.
