Jonas Brothers Bring Canadian Rock Band The Beaches Onstage In Vancouver

The Beaches just got a big nod of approval from Jonas Brothers.

On Saturday night (Nov. 11) at Vancouver's Rogers Arena, Jonas Brothers welcomed the "Canadian darlings" to the stage to play their breakout hit "Blame Brett." The impromptu performance took place after an intermission midway through Jonas Brothers' own set.

“Words cannot describe what this meant to us as lifelong fans, but just know we’ll probably be talking about this until forever,” the band wrote in an Instagram post.

Already charting on a number of different Canadian rock and radio charts, the band recently made their U.S. Billboard debut on the Alternative Airplay chart with "Blame Brett." It peaked so far at No. 22 and is currently in its sixth consecutive week on the chart.

The song's opening lines have become ubiquitous on certain corners of Canadian social media: "Done being the sad girl / I'm done dating rockstars/ From now on only actors / Tall boys in the Raptors."

This isn't the first big American band that's given The Beaches props in recent months. In September, the band caught Blink-182's Mark Hoppus singing and bopping along to "Blame Brett" on a livestream.

It's also not the first time Jonas Brothers' have interrupted their own set with a special guest. They surprised and confused an audience with a performance by the duo behind the viral Eurodance parody song "Planet of the Bass" back in August.

The Beaches are currently finishing up a North American tour. They played Vancouver's Orpheum on Sunday, the night after their appearance at Rogers Arena, and will finish this leg tonight (Nov. 13) at the Royal Theatre in Victoria. They'll continue touring in Europe then back to the United States until March, 2024.

Composed of Jordan Miller, Kylie Miller, Leandra Earl and Eliza Enman-McDaniel, the band formed in 2013 in Toronto. The song explores lead singer Jordan Miller’s break-up with Brett Emmons, frontman of Canadian Rock band The Glorious Sons.

Tickets for the final half of The Beaches tour are available on Ticketmaster.
