MISSOULA, Mont. -

One of the best selling musicians in history made more history on Thursday in Missoula.

At 10 a.m. tickets to see Paul McCartney went on sale at the University of Montana box office, and in just 2 hours, box office workers say they sold almost 25,000 tickets, quickly approaching the 25,218 capacity at Washington-Grizzly Stadium.

Adams Center Executive Director Brad Murphy says that is the most tickets sold for a concert in the shortest amount of time in Grizzly box office history.

The previous concert record was set by the Rolling Stones in 2006 when 23,100 people filled the stands at Washington-Grizzly Stadium to see them perform.

McCartney is one of the biggest musical draws to play Missoula since then. Murphy says most ticket buyers bought online, but several hundred people lined up Thursday morning to buy tickets at the box office.

16-year-old Missoula resident Chase Koenig camped out at the box office overnight to be first in line.

"Paul McCartney's a legend,” said Koenig. “He's one of the most influential musicians of all time, and when he comes to Missoula, you've got to see him."

Missoula resident Mike Jakupcak, who also stood in line to buy McCartney tickets, says he watched the Beatles play on the Ed Sullivan show in 1960, and he says he can’t believe he’ll get to see one of them play in person.

"I'm amazed by Missoula, to think that we've had the Stones, and Elton John, and Joan Baez, and the Beatles,” said Jakupcak. “It's a remarkable experience for Missoula."

McCartney plays Missoula at Washington-Grizzly stadium on August 5.
