I was also there! good times. I was the University of Lethbridge Mascot(Pronghorn). I was lucky and got in at #24 which was perfect because I don't know how much longer I could have handled wearing that costume without suffering from deydration. Either way, good luck man!
Here's the video that I sent in originally...It is just a crappy song I wrote in a day or so for them. Don't expect much haha, but atleast it got me a callback
