I’ve said this before: if I had a time machine, I know exactly what I’d do with it.  No, I wouldn’t steal a sports almanac or try to get my parents to kiss at the big dance. I’ve already graduated high school, so I wouldn’t use it to pass my history final, either. No, I would head back in time at 88.8 miles per hour to the Copa Room at the Sands in 1960, to see the greatest show one could see for $5.95. Dinner included.Like many of you, I have a decidedly romantic view of “old Vegas.” A time where women were ladies and comps were truly comps. When men wore hats (thanks for nothing, JFK).  And when you could see a legend performing in the lounge. Often for free.I also have a decidedly romantic view of the mid-century crooners. Dean Martin, with a voice dark and syrupy like bourbon, and a total cheeseball when live on stage. Sammy Davis Jr., the most talented of them all, who could sing, dance, and act all his contemporaries under the table. And of course, the man himself: the Chairman of the Board, the one who made loneliness seem cool: Mr. Francis Albert Sinatra. When I want to relax for the evening, it’s an old fashioned in my glass and the Rat Pack on my stereo.Despite peaking in Las Vegas 60 years prior, the Rat Pack is also inextricably intertwined with our Vegas trips today.  The men of The Summit provide the soundtrack to our early evenings. While we shower and dress for an evening on the town, pre-dinner cocktails in our hotel room glasses, Sammy, Frank, and Dino provide the soundtrack. No two days in Vegas are the same; but the Rat Pack is part of the ritual that binds them together for my wife and I. Indeed, the bellman has no sooner closed the door and my wife is asking me to turn on the Bluetooth speaker and put on music. Not just any music; our Vegas music.  The only music that will do.When planning a recent trip, I mentioned to my wife that there was a Rat Pack impressionist show a little off strip. “And why haven’t we seen it yet?” Was her response.  “The Rat Pack is Back” is not a new show to Vegas.   With a history of more than 20 years, the show was previously at several venues in Vegas, including the Rio and the Plaza before finding its current home at the Tuscany, just east of the Strip on Flamingo in 2015.  In fact, if you’ve seen the movie Get Him to the Greek, you’ve seen a little of the Rat Pack is Back show at the Plaza.  Russell Brand’s character musician stops by to see his dad, who is a drummer in the show.I’m not sure what I was expecting when I purchased our tickets to The Rat Pack is Back… Maybe 80 minutes or so of mediocre, karaoke-style covers of my favorite songs? What we experienced ended up being so much more, and it’s a show that we will definitely be returning to see again.The Rat Pack is Back is performed in a small theater at the Tuscany in Las Vegas, in an intimate venue appropriately named “The Copa Room.” It features 3 impressionist performers, of which 2 are great and 1 is just okay.  (Our Dean Martin didn’t really look or sound like Dean Martin. I’m looking into whether he was out for the night, or just plain out.)An especially enjoyable aspect of the show was the live, seven-piece band backing the trio.  I often caught myself watching the piano playing conductor as she guided the band through their various cues. True to their subjects, the band and impersonators often had moments of playful banter between them.The Copa Room at the Tuscany is unfortunately a shadow of its namesake at the Sands, but this didn’t take away from our experience.  A relatively small-for-Vegas room, seating consists of movable “wedding venue” seats, with small cocktail tables between the front VIP tables. Lucky for us, the small size of the room contributes to a more intimate setting.  Seating is assigned by “area” and is first come, first serve. I paid for VIP seating, and we arrived early enough to be granted front row seats on stage
