Don't look for Santa at the Mondays Dark year-end bonanza. "Nobody is singing 'Jingle Bells,'" says host and founder Mark Shunock. Instead, the six-year anniversary party is embracing the holiday spirit at a more elemental level. If you're looking for a reason for the season, this is it: the community coming together for some great entertainment and lots of giving.

For those not in the know, Mondays Dark is a twice-monthly charity variety show featuring a full band and a rotating, volunteer cast of Strip performers and local personalities. Each event raises $10,000 for a different local nonprofit organization. The December 9 edition will mark the 100th beneficiary, which means Mondays Dark will hit a massive charitable milestone that night. "It's our $1 million night," Shunock says. "It's crazy to think that [these] $20 [tickets] have added up to a million."

Normally, Mondays Dark takes place at the Space—Shunock's multipurpose event venue—but for this special anniversary event, it will move into a much larger room: the Pearl at the Palms. The Pearl holds more than 2,000 people (compared with 350 at the Space), and Shunock expects a sellout. He has invited all 21 of Mondays Dark's 2019 charity partners to attend the event, where he'll reveal the 21 planned charity partners for 2020.

(This year's charity partners included the Las Vegas Rescue Mission, After-School All-Stars, Big Brothers Big Sisters, Nathan Adelson Hospice, Pawtastic Friends, Discovery Children's Museum and Majestic Repertory Theatre.)

"Forty two local charities will be in attendance at one event—all supporting each other, not competing," Shunock emphasizes.

Along with the entertainment, the sixth anniversary event will include live and silent auctions, along with a charitable call to action. Shunock is keeping further details secret for now, but says the surprise will involve all the charities and entertainers, plus the casino chapel.

Shunock himself is another big draw. You might know him as the host of Vegas Golden Knights games and Top Rank Boxing events. A starring role in the now-shuttered Rock of Ages brought him to Vegas, and he has gone on to become a local star, opening the Space in 2017.

As for who else will perform at this stellar event, that's also under wraps. "What makes Mondays Dark special is that it really is never about the [specific] entertainment; it's more about community coming together," Shunock says. "Our supporters understand that. They just come because it's a Mondays Dark event."

One person you can expect to see, however, is singer-songwriter and entertainer Travis Cloer. He's best known for playing Frankie Valli in Jersey Boys, and he recently released a new album, Here's Travis Cloer. A very close friend of Shunock, Cloer was one of the first musical guests to perform at Mondays Dark, and he tries to be in attendance whenever his schedule allows. "It's just a lot of fun; you never know what's going to happen," Cloer says. "There's always a surprise. It's just a great time for everybody."
