Stevie Wonder truly is a legend among us, and every now and then he decides to flex a little bit, humbly reminding us of the undeniable fact he is one of the best to ever do it.

The multi-talented icon was recently in California for the National Association of Music Merchants (NAMM) conference, and while he was walking through the lobby of the Anaheim Marriott over the weekend, he found himself inspired to break out into an impromptu performance alongside busker Grayson Erhard.

As reported, at the time, Erhard was performing Wonder's 1972 hit single "Superstition," but was struggling to remember the words  to the second verse (likely because he realized who was in the audience).

Wonder, being the absolute sweetheart he is, decided to hop on stage with him, and turn Erhard's performance into a once-in-a-lifetime duet, clearly forgiving the musician for stumbling over the lyrics.

"We celebrate the March on Washington, all the women of the world," Wonder says after inviting himself on stage. "Cause you're one of the reasons we're here."

From there, the iconic musician is in performance-mode, handing over the mic to Erhard to get the song started again with his expert guidance. 

Take a look at the footage of the incredible moment and hotel lobby performance in the clip below.
