WICZ.com: Starkid's 'A Very Potter Musical,' born at U-M, staged in Binghamton without permission
Starkid - the production company formed by the former U-M students involved with "AVPM" - is less than pleased, not only because the Binghamton group didn't seek permission to do the show, but because Starkid has been careful to avoid anything that might open them up to litigation related to copyright issues.
"AVPM" - which starred, and had music written by, "Glee" star Darren Criss - has managed to avoid legal problems thus far by way of Starkid never charging money for tickets (for "AVPM" or its follow-up, "A Very Potter Sequel") and categorizing "AVPM" as an "unofficial, fan-made parody show."
On Monday morning, StarKidPotter's Facebook page offered this quote, with a link to the WICZ.com story: "Well this is not cool. You all know us and know that we are big charity folks, but these guys did not get permission and we are the ones who have to deal with the WB. You all know that, but obviously some don't care. Please let them know how you feel and for those of you who have asked to do any of our shows and were turned down that we never say Yes to anybody and that we did NOT give the OK for this."
