I wrote fic! I'm wayyyyy too lazy to deal with copy/pasting a large amount of text and yelling at my Opera browser because it makes lj cuts difficult, so I'll post a link to where I posted it on FFnet. It's pretty ridiculous, and if you haven't seen A Very Potter Musical you won't get the main joke. But it has Marauders and Lily, so they're pretty awesome!
Because Darren Criss would make a better James, anyways. (I realized after I posted this that a story like this is just begging for publicity. I don't want to whore myself out, in a fanfiction sense, but I guess referencing AVPM is bound to increase my FFnet visibility.)
