Is Garth Brooks performing at The Grizzly Rose on Thursday?

Is “Yukon Jack” playing The Grizzly Rose Thursday?

OK Denver, put on your boots and grab your detective hat, because we’ve got a mystery — and honestly it’s not even that mysterious.

Garth Brooks is set to perform four arena concerts in Denver this weekend, but country music fans are convinced there’s a secret fifth show happening Thursday night at a much smaller, much more iconic venue.

The Grizzly Rose in north Denver has a concert listed for Thursday at 7:30 p.m. — featuring an act called “Yukon Jack.”

Interesting.

A quick Google search turns up exactly zero musicians named Yukon Jack. However — and here’s where it gets fun — Garth Brooks is from Yukon, Oklahoma, and he famously used the “Yukon Jack” alias at a small bar back in 1993. Brooks also told 9NEWS last month he’d love to return to The Grizzly Rose, where he performed early in his career.

So yeah. We think we know who “Yukon Jack” is.

Here’s what you need to know if you’re going for it: Tickets are cash at the door only, and you cannot line up on Grizzly Rose property before 4 p.m. Thursday.

Good luck — you’ll need it.

This is the most fun Denver’s had solving a mystery since…ever.
