Actually that song is called "We're gonna take on the world" by Mustard plug off their album Pray for Mojo ($@#$@#$@#$@# me and my radio impulses.) They're a really good ska band but I don't know if that was a cover or not.
We have another video thats a tribute to the six weeks that I made as well in addition to this one. It might be playing in our pits during nats but if you're interested, heres that movie. Its more of an in-joke than anything else. The music is mix so if there are any you're interested in, contact me.
