Rocky Horror Picture Show

[cowboystracker.livejournal.com]

I checked holidays, movie tie-in, crossover, and a couple of others under the tags and the memories but haven't found the fic I'm looking for. All I remember is Brian shows up at Emmett's apartment (Michael might still be living there too) before a Halloween party at Babylon because he thinks that Justin is going to be dressed up as Janet and he wants to stop him. But if I remember correctly it turns out he's dressed as Dr. Frank-N-Furter. I could be wrong. I think Ben was dressed as Rocky, Michael as Riff Raff, and Emmett was dressed as Janet. Anybody know this fic?
