In the great abyss that is our World Wide Web, sometimes—just sometimes—the People of the Internet can work together for good. And when it happens, it is magic.

Last week, Reddit user im_not shared a YouTube clip of an elderly man playing the piano in Reddit’s Videos community. The song was “It Might as Well Be Spring” from the 1945 film “State Fair.”

There’s nothing particularly striking about the video—the man is sitting alone in a small bedroom—but the performance is beautiful, cathartic. A scroll through his YouTube profile, happypiano1, would lead you to similar videos—he’s played musical classics such as Gershwin’s “Someone to Watch Over Over Me” and Rodgers and Hart’s “You Are Too Beautiful,” along with many church hymns.

His fingers dance on the keys with gracefulness and ease, and his expressions show pure contentment.

But, as im_not noted, “He stopped uploading a few years ago and I don’t think he ever had much of an audience.”

Redditors began wondering about him.

“I honestly almost cried when I saw his channel name was ‘happypiano01,'” wrote Reddit user breadpoetsociety. “I love this man. Thank you, Wally.”

“That hit me the hardest,” added Reddit user fleashosio. “Probably some guy that didn’t fully understand computers or the Internet, possibly. But he really loved playing the piano and knew that it was possible to share his music with everyone around the world. So he did anyway. It’s like when my parents or grandparents use the internet. They don’t really know what they’re doing, but they try their hardest anyway because they just want to make someone smile.”

Some thought the man might have passed away, but then found clues that he was alive: his wife’s obituary (which lists him as a surviving family member), his son’s piano-tuning website (which mentions his dad being his best client), and finally, the golden ticket: a recent photo of him on Facebook.

“Wally Krauss, is alive and well he recently played at a retirement home,” wrote Reddit user ur_mom69. “Chill guys he’s alive, and old.”

We called his son. John Krauss, a piano tuner, told us that we found the right person—he is the one who has recorded videos of his father playing the piano. And yes, he’s still alive.

Walter “Wally” Krauss is 93 years old and lives in Lansing, Michigan. John says he has a few health problems, and he fell and sprained his hand last year, but he has recovered and is still “the most optimistic guy around.”

For Wally, music was never his full-time profession. After graduating from Northwestern University, he became a corporate credit manager and treasurer for a steel service center in Chicago. But music was what has always guided his life. John says his father was the organist and choir director for his church, and he continues to play the piano at neighborhood senior centers.

On why he decided to create a YouTube channel for Wally, John says, “I just felt his enthusiasm needs to be shared. I said, ‘We need to share my dad!'”

“[Dad] never said, ‘Hey, record me,'” John adds. “He never cared about having an audience. If there were two people in the room, that was his joy. He cared about friends and people having fun around the piano.”

After gaining a small Internet following through YouTube, John would print out the nice comments, put them in a notebook and read them to his father. John even translated the ones that were in Spanish.

“He loves the feedback,” John says. “He’s almost 94 and still going!”

John then put us on the phone with his father, the one and only Walter Krauss. Here’s what he had to say about music and life.

Thanks for taking the time to talk to me, Wally.

At my age, time is important. I’ve got a lot to live for! [laughs]

Do you know what YouTube is? What what is? It’s a video website on the Internet where so many people are finding and listening to your music. Yeah, I don’t understand that. [laughs] Well, thousands of people are inspired by you. I play every day. I don’t miss a day. That’s what I do. Play music. It’s the first thing I do in the morning. My dog Brandy wakes me up, I take a shower and head to the piano. It’s in the living room. It’s a keyboard. It’s a very good one. And the other piano is in my bedroom. It’s a regular piano. I practice for a good hour. And people apparently like it. [laughs] Who taught you how to play the piano? Oh, golly. He was the pastor of the church I attended. He had me play for the congregation. Then everything changed and they moved the piano to the back end of the church, upstairs. But still, I played music every day. Do you have any favorite composers? I’ve got a book full of them here. I have two different books. What advice do you give your children, grandchildren and great-grandchildren? They should make sure they get to church. And enjoy the music. Is there anything else you’d like to add? I’m just a lucky guy, that’s all! Since receiving all the attention, happypiano1 gave fans what they were looking for—another piano performance and proof that Walter is doing just fine. Reddit user jdog90000 announced in the Videos community, “We did it Reddit! After 3 years, Wally Krauss has uploaded a new video!” The description reads, “Wally says: ‘This song is dedicated to music lovers everywhere and all of my friends on Reddit!””

Thanks for the music, Wally.
