The New Orleans Swamp Donkey's (which, by the way, is the greatest name for a band ever) hosted an evening in New York this Monday, and seeing as fever pitch for Game of Thrones is at an all time high with the forthcoming season finale, they gave fans a treat. Thankfully someone was there to capture it all.
