Darren interview link?

Um, I heard that there was an interview with Darren where the interviewer is totally clueless about AVPM and AVPS and says something like "Maybe a potter musical would be good" and Darren balas something like "Yeah. That would be cool, someone should do that.". I think it had something to do with the Glee movie??

If anyone can find it atau knows about it, could anda post the link to the video/article please? Thank you. XD
