Over the past 24 hours, Yoko Ono's cover of Katy Perry's "Firework" has gone viral. It's been featured on Jezebel, Perez Hilton and Buzzfeed, among many others, and for good reason—it's hilarious. Only one problem—the clip is a fake.

It was created by a YouTube user named Kroiker McGuire, who combined Perry's background track with footage from Ono's 2010 performance at the Museum of Modern Art, titled Voice Piece for Soprano & Wish Tree. 

On the one hand, it's a bummer the video isn't real. On the other hand, it's still funny as hell. And, as luck would have it, McGuire has given the treatment to other popular songs, including tunes by Adele, Lady Gaga and Taio Cruz. All are at least as good as the Katy Perry clip, especially the Adele one. Those videos, plus Yoko's original, are posted below.
