(Update at bottom)
A street performer was sitting outside a Kroger in Texas playing his guitar and singing when he was approached by a couple strangers who started singing with him....
So great. By the end of the song three guys started jamming. This truly is music in its simplest form.
Over 5.6 million views in 3 days... wow.
UPDATE: Jimmy Kimmel had them on to perform. Jimmy joins in on saxophone and then Trey Songz, Juicy J and Aloe Blacc come out and join in.
