I love this show choir video so much!! It's the North Central Counterpoints from 2009.  The song is really great and I just love their tapping.  (Their taps are Converse - how freaking awesome is that?!) I'm not really fond of the beginning part, but if you start it at 1:25, it's really good.  The song is from the musical "In the Heights" and it about a lottery for $96,000.  My favorite part is when everyone starts singing all different things together towards the end.
