The reigning viral video of the week is this clip of an impromptu jam session that broke out among three strangers in front of a grocery store in Irving, Texas.

The video has accumulated 10 million views on YouTube since Saturday. As Jimmy Kimmel explained on his show last night, people started contacting him asking him if he had orchestrated it. Kimmel hadn’t played a part in the original, but he invited the guys on his show to reenact the moment with some extra fanfare and surprise guests. By the time it was all over, Kimmel and his band plus Trey Songz, Aloe Blacc, Juicy J, and a gospel choir had all gotten involved. Watch that spectacle below.
