Even if you don’t love Bon Jovi, chances are you still know a few words to their 1986 classic “Livin’ on a Prayer.” The song is belted during late nights in bars, on the dance floors at weddings, and, as it turns out, on a random day in a London park. Matej Priteržnik uploaded a video to YouTube in which a man begins singing the song—by himself, at first, until a crowd joins him in the chorus. It’s a spontaneous, magical moment that you’ll only see when you step outside of your home.
At just 46 seconds long, Priteržnik says in a YouTube comment that he captured the video clip just to have a memory of it. He shared it online to demonstrate a larger message: “That one guy can change everything!” The sentiment echoed in the other comments. “This video is amazing, and highlights humanity and the community that exists deep in us all,” one viewer wrote.
This isn’t the first time that the man featured in the clip has seemed to randomly break into song. Last fall, a video was uploaded featuring a singer—who sounds a lot like the guy in the park—serenading a subway car with the same Bon Jovi bop.
