'It's been an amazing journey': Singing Mayo Clinic surgeons bid farewell to Minnesota

The singing surgeons from Mayo Clinic are bidding farewell to Minnesota as they finish up their residency at the clinic, ABC affiliate KAAL-TV reports.

It took just one video posted online to change their lives.

"He was like, 'Hey, can you put a piano accompaniment together for this, and I did, and we did it, videotaped on like an iPhone 6," said Dr. William Robinson. "Power of the internet."

The video of Robinson and Dr. Elvis Francois went viral in 2018, and since then, they've made national appearances.

Wednesday, finishing up their residency at Mayo Clinic after five years, they held a mini-concert at Forager Brewery to say goodbye.

"Not in my wildest dreams could I have imagined reaching so many people," Francois told KAAL.

"We're training to help people with medicine but it's incredible to see that music helps people in ways that medicine simply can't," he added.

Even with the national recognition, they say nothing compares to a heartfelt note.

"It's the Facebook messages, the Instagram messages that are not only just kind words, 'Hey, keep doing what you're doing,' but also, 'Hey, I've lost a loved one, hey I've got a diagnosis of cancer … and this touched me I needed to hear this,'" Robinson said.

"Knowing that we can do this and brighten people's day, there's honestly no other way to describe it," Francois said. "It's been an amazing, amazing journey."

KAAL reports Francois will head to Boston while Robinson will move to Philadelphia.
