I'm assuming this was unrehearsed and the playing impromtu? If so, it pulled together well considering the large group. Looks like two harmonicas were in hand, need to go back and listen again. My son and I will be performing this song next weekend. He on guitar and me on harmonica.

Around 5 minutes in there is a guy who is dancing while doing some kind of percussion with his feet. Do you know what he's using exactly?
Really nice overall! They did a great job layering all of the sounds and highlighting them and taking them out, so it felt like for each section you got to appreciate a different aspect of the instrumentation. Quite impressive!
