Hot tickets for the much-anticipated performances of Broadway show "The Book of Mormon" at the Denver Center for the Performing Arts went on sale Sunday morning and sold out in about five hours.
Fans who tried to buy tickets online complained about the theater's bogged down website.
The "Book of Mormon" is the musical brainchild of Colorado natives and South Park creators Matt Stone and Trey Parker.
The show doesn't hit Denver until August. But with hundreds of fans standing in line for hours on Sunday, tickets sold out by about 3 p.m.
Would-be buyers voiced their frustrations on the DCPAs Facebook page, although many posted that they were finally successful, some after hours of trying.
One user posted, "Finally got my Book of Mormon tickets after 100 minutes of unsuccessful website browsing on Denver Center for the Performing Arts site. #FAIL."
DCPA spokeswoman Heidi Bosk said the site hadnt crashed; it was just overwhelmed. Bosk said the DCPA was excited about the response.
The musicals website suggested that fans struggling to make an online purchase might have more luck in person.
Julio Becerril showed up at the theater in his pajamas to buy tickets after he and his brother ran into problems buying them on the website.
"He told me, 'Just come on down. We're going to go down there,'" Becerrill told 7NEWS. "I didn't have time to change. So we've just came down here. We've been waiting for like three hours."
Unsuccessful ticket-seeker Michelle Garcia said, "I'm just bummed out that I wasn't smarter and camped out with everyone else overnight."
A Denver Center for the Performing Arts official said extra staff was brought in to cope with the unprecedented demand.
"I think they get the magnitude of this, that it's a very exciting show to be launching in the creators' hometown," said Denver Attractions spokesman Jeff Hovorka.
