The North Pole is a pretty raunchy place. That’s what the Yellow Tape Construction Company would lead you to believe, anyway. And while we don’t remember Frosty the Snowman dealing smack in any of the Christmas fables we used to read in kindergarten, it’s not implausible. He may be a sentient amalgamation of button, coal, and corncob, but he’s still a man—and, just like the rest of us, Frosty is constantly at war with his inner demons.

It’s this re-characterization of the perennial icons of Christmas lore that drives the Yellow Tape Construction Company’s sometimes poignant, sometimes puerile but always charming The Ultimate Christmas Musical: The Musical. And it’s exactly why we would no longer be surprised to see Frosty, top hat in hand, waiting anxiously in line at a methadone clinic.

The Ultimate Christmas Musical: The Musical is Yellow Tape Construction Company’s seventh production and third musical. It takes place in a North Pole populated by nymphomaniac elves, philandering reindeer, and a Santa Claus so beleaguered by burgeoning disbelief in his existence that this year’s Christmas would take a miracle to pull off.

The story follows the kind of standardized plot line you’d expect from such an allegorical undertaking: Santa saves Christmas. And that’s a good thing. The absurdity of the characters in TUCM:TM—their crass insults, their pointed dialogue, their tongue-in-cheek cultural allusions—overshadows the development of the story to become the focal point of the show. The humor of TUCM:TM presents itself in the way its characters, exaggerated reflections of reality that they are, interact with each other within a realm of fantasy that is usually reserved for playful holiday piety.

“We spent a lot of time trying to write it from our perspective and have a good sense of humor and carry the kind of cynical, smart-ass crassness that all of the stuff we do has,” said Jonathon Morgan, TUCM:TM’s director. “But it’s still a Christmas musical. We didn’t want to write an anti-Christmas musical; that would be lame. We all like Christmas, so it would have felt stupid to make fun of it the whole show.”

As a musical, TUCM:TM fully provides, with little more to be desired: A full band (drums, keyboard, saxophone, clarinet, guitar, standing bass, and backing vocals) drives the interstitial musical performances, which are well-rehearsed and act as apt transitions between scenes. In fact, one of the things we were most impressed with about TUCM:TM was the degree to which everything had been mastered. For a show that runs longer than an hour, we can’t remember a single line that was flubbed or dance routine that fell flat—and we saw the show on November 30th, the second day of its run.

We’d guess that TUCM:TM unfolded so fluidly in performance because the players seemed to be having so much fun. It’d be hard not to: The sprightly dialogue is witty and light, the characters are unapologetically randy, and, perhaps paramount to everything else, Christmas is a fun time of year. TUCM:TM is like a theatrical version of the regional sales manager drunkenly photocopying his bare ass at the company Christmas party: It reminds us that donning a Santa cap can be justification enough for letting loose.

Ultimately, Yellow Tape Construction Company’s The Ultimate Christmas Musical: The Musical is a funny, fun, endearing musical pilgrimage across the plain of American holiday tradition.
