The Clarks traded a traditional concert stage for City Hall on Wednesday, performing a three-song set in the Pittsburgh mayor’s office.

The performance — which Mayor Corey O’Connor billed as the first concert ever held in the mayor’s office — kicked off with the band’s 2000 hit “Born Too Late.”

A few dozen city staffers and council members crowded into the room to listen, snap photos and sway to the music. O’Connor, who joked he’d be known as Corey O’Concerts for the day, seemed to quietly sing along. Blue, green, red and orange lights illuminated the entrance to the mayor’s conference room behind the four-man band.

Lead singer Scott Blasey said the band would’ve never dreamed when they started playing covers at Indiana University of Pennsylvania 40 years ago that they would one day become the first musical act to perform in Pittsburgh’s mayor’s office.

After thanking the mayor for inviting them to perform, Blasey acknowledged fans who could watch the show via a livestream on the city’s YouTube and Facebook pages.

“Your passion for our music is something we’ll never take for granted,” he said.

O’Connor presented the band with a proclamation and declared Wednesday The Clarks Day in the city of Pittsburgh before the band broke into a second tune, “Penny on the Floor.”

The band was initially scheduled to play two songs, but performed a third after a staffer called for an “en-Corey,” using a play on O’Connor’s first name and spurring the mayor to call for “no more puns.”

The Clarks finished their roughly 15-minute performance with “Better Off Without You.”

The band will host a 40th anniversary concert at Stage AE this weekend.

In January, The Clarks released an EP titled “Echoes from the Pitt.” The album featured a re-recorded version of “Better Off Without You,” a song that was recently featured on the HBO Max hit series “The Pitt.”

The mayor, after the show, told reporters he hoped to use the performance to highlight the city’s local music scene and the historic City-County Building, which was opened in 1917.

“That’s what this office is for — to tell the Pittsburgh story,” O’Connor said.

Plus, he joked, there’s a big perk to attending a concert in the mayor’s office over a larger venue: “There’s less traffic leaving this concert.”
