I was hoping you guys would be able to help me find a fic I read a few years ago.

It was an spn/American Idol crossover, set in a world where the supernatural isn't real, and where Sam and Dean both sign up for American Idol. With several other spn chars participating as well.
And it turns out that Dean had to have John institutionalized because he became a threat to Sam.

Anyone know where to find it?
