The Toronto choral cover group Choir! Choir! Choir! plans to stage a concert at the United States-Mexico border on Sunday.

A post on ticketing site Eventbrite says singers of all levels can participate in the show, which will take place in two locations at the same time — at Border Field State Park in San Diego, Calif., and in the nearby Mexican border town of Tijuana.

Canadian artists Nobu Adilman and Daveed Goldman founded Choir! Choir! Choir!

The two invite strangers to gather at drop-in sessions around North America to learn harmonies and sing a designated song in concert together for free.

Up to 500 participants will be able to gather at the event in San Diego and about 300 in Tijuana.

Adilman, who is usually the group’s conductor, says he’ll be onstage leading the singers in Tijuana while Goldman does the same and plays an acoustic guitar with those in San Diego.

They’ll all sing “With a Little Help from My Friends” by the Beatles.

“We’re not trying to make this a political event,” Adilman said in a phone interview.

“The event is about communication, it’s about keeping doors open and keeping the conversation going. We’re better when we come together to celebrate each other, and just the simple act of singing together is a jumping-off point for so many beautiful ways to connect, beyond the singing.”

Adilman said they plan to shoot video of the event with the organization ArtPower.

The Eventbrite invitation says online registration is required but does not guarantee admission.

It says the purpose is to “celebrate the unique friendship, culture, and community we share in the border region of San Diego and Tijuana.”

“There are few places on earth so scenic where you can gather people from two countries at once to create beautiful music together and share in how special it is to be in this particular place in the world,” says the Eventbrite post.

“While we will be divided by the physical border, music knows no boundaries and our voices together will transcend barriers.”
