Musician Jokingly Plays Few Chords Of A Famous Song, Crowd Goes Wild, And There's No Turning Back

"What's happening?"

Spicing up your music gig with someone else's song is not always a rock-solid idea. Unless that someone else is the legendary rock band AC/DC.

When American folk-rock singer and songwriter Matt Nathanson was performing live with his band at the Upstate Concert Hall in Clifton Park, N.Y., Nathanson decided to surprise the crowd by playing a few chords from AC/DC's hit "You Shook Me All Night Long."

Little did Nathanson know that he'd be the one standing in awe.

Just as people's ears recognized the familiar melody, they bursted into an impromptu sing-along, making the band shrug and wonder what the hell was going on.

But after a few milliseconds of confusion, Matt and his buddies joined in, delivering the best performance that you can watch below:

Seems like a truly beautiful moment shared by both musicians and the crowd. Have you ever witnessed anything similar? If so, share with us!
