That's a clip of the Aggrolites performing the classic song, "Banana" (with modified lyrics of course) for the television show, "Yo Gabba Gabba!" If you folks haven't been watching this show, then you have NO SOUL! Just kidding. But seriously, watch it.
I kinda wish that the Aggrolites would play this song more often live! I still remember hearing it for the first time in a small ass venue on a cold December night in 2003...it was my first time seeing the Aggrolites, and it was the moment that made me fall in love with this band!
