Watched Matisyahu joins coffee shop performer on "One Day". by Matisyahu from YouTube

This was rad. This kid started singing Matisyahu's "One day" and didn't know that the artist was right in front of him. Watch the reveal at the end. He still didn't believe it was him and it took a second for it all to sink in. Loved this moment. Update: the kids name is Kekoa or aka Clint Alama.
