Be sure to bone up on your lyrics before performing in a hotel lobby, because you never know who might come meandering by to listen.

Rolling Stone reports on a wonderful video that has captivated the Internet recently.

It features a beautiful moment when singer Grayson Erhard, performing the song “Superstition,” happened to spot icon Stevie Wonder in the audience.

Erhard explains on YouTube that he had just finished his rendition when, well, it’s best if you just take a look at a truly remarkable moment.

Things get good immediately as Erhard exclaims: “Stevie, I’m sorry. I don’t actually know the second and third verse, yet. But that is so cool, oh my god.”

Rather than walk past a moving moment, Wonder gets on stage, tosses out a hat tip to the women marching over the weekend and helps the singer finish off the song with the remainder of the lyrics.

As the report explains, the entire song went down at the National Association of Music Merchant's 2017 convention on Saturday.

In this particular case, the scene was the lobby of the Anaheim Marriott, where, apparently, just about anything can happen.
