So, Vogue did quite a hack job on its Glee Fashion’s Night Out photo. It was like they weren’t even trying! The video promo, however, is decidedly less fake.
It looks like the entire cast (except Naya Rivera and Amber Riley, that is) were indeed in the same room, meaning the final image was a composite of several different pics from the same shoot. Anyway, the Glee kids sing David Bowie‘s “Fashion”, and Sue Sylvester makes a surprise appearance at the end.
