So I was looking through youtube the other day and randomly decided to search for The Onion Cellar, even though they said all electronics were prohibited. I found a video of part of their introductions song, which was the very first thing. It's not the entire thing and Amanda changed it each night, this was recorded the night after I went to see it and it is really different.
Note: The video really sucks because they are trying to get to many things at once but it's the best and only thing there is of it.
