NORTHAMPTON — While social media and pop culture may feed the impression that music and dance are monopolized by the young, the Young@Heart Chorus emphatically debunks this as a myth.

And according to Bob Cilman, the 42-year-old group’s founder and orchestrator, “we’ve never been so old before,” speaking at rehearsal for the group’s next concert taking place at the Academy of Music on Sunday in collaboration with LightHouse School of Holyoke. That performance, appropriately named “Old School,” will feature eight members in their 90s, and an 102 year old.

Since its founding in 1982, Y@H has emerged to be globally recognized for their chorus of members who are “forever young,” with membership ranging between the ages of 74-102. The group’s oldest members, who will be in the spotlight on Sunday, shared that for them Y@H has been an antidote to loneliness and seclusion, and the reason why they as a group have been able to not only maintain their energy and talents, but also their smiles.

At 95, Steve Martin is among the oldest chorus members. He joined more than two decades ago after his wife, now deceased, recommended he give it a chance.

“Music is so good for you. It is so good for the elderly,” said Martin, noting that music has played a key role in maintaining his health and keeping his mind stimulated.

“Kids tell me all the time they wish their grandparents were doing this,” he said, adding that the young are quite captivated when he shows them he can rap.

“The problem is we don’t focus on the elderly enough,” he said, noting that advertisements and culture are catered to the young because they are the most likely to buy things.

Dora Morrow, meanwhile, joined Y@H in 2002 when she was 80. She’s now 102.

“They’re just a nice group to be with and they love to travel. And that’s my lane — travel,” Morrow said after rehearsal on Monday. The group’s oldest member will show off her skills on Sunday with a solo.

Other chorus members over 90 to be featured on Sunday include Gloria Parker, 96, Helen Boston, 95, Pat Booth, 92, Norman Moreau, 91, and Anita Shumway, 90.

Travel became a feature of the group after an all-time top 100 box office documentary catapulted their popularity in 2007, leading them to perform around the world, including New Zealand, Europe, and Japan.

Now, less then 20 years later, the group has garnered international attention, and has been highlighted by various mainstream media outlets.

Parker said that when she joined Y@H in 1995 she had no anticipation the group would go on to perform more than 50 international tours, but that for her too the traveling aspect has been one of the most enriching for her.

“I love the camaraderie, and the traveling has been amazing,” she said.

In Martin’s words, “We went from doing schools and local stuff ... to all of a sudden we got some people from Europe interested in us,” referring to British producers who filmed the documentary for Fox Searchlight.

Y@H is made up of a collection of people from across western Massachusetts, and not exclusive to those with a background in performing arts. While Morrow and Parker have sang in the past, Martin grew up in Detroit which at the time was a booming immigrant city, later becoming an engineer in college. Immigrant Detroit, he said, is where he was introduced to music by all the various traditions and cultural backgrounds of his neighborhood.

The elderly ensemble performs covers of music, with themes that include resisting loneliness, craving affection, wanting to love, the phenomena of regret, and even the joys of letter writing — human emotions nobody matures out of.

Songs with uplifting bass are followed by ones with somber percussion, ushering an experience for their audiences that allows both escapism and reflection, and forms a sound that is fresh and new, but laced with nostalgia and timelessness.

The group will continue rehearsing this week at LightHouse School in Holyoke, which is partnering on the production of “Old School.” The partnership began earlier this year when LightHouse bought Gateway City Arts complex, where the Y@H has rehearsed since 2015, on Race Street. Sunday’s show is being produced by Y@H and LightHouse’s De la Luz Technical Arts Institute.

“They’ve been so generous to us at LightHouse,” said Cilman.

Part of the partnership for “Old School” is Isaac Littlejohn Eddy, a former Blue Man Group performer and theatrical director at LightHouse who will serve as guest theatrical director for the Sunday’s show, which will also feature various members of the school’s staff, including students, pitching in.

“I hope that this is the beginning of many projects with them,” said Littlejohn Eddy, who said that the joint effort is exemplary of the school’s goal to “collaborate with different artists in the community.”

Tickets for the 3 p.m. show can be purchased online, or at the Academy of Music Box Office, open Tuesday through Friday from 3 to 6 p.m.
