See Yoko Ono Sing Katy Perry.

The only question I have to this entire video is "Why?"

Still she DID break up the Beatles and made John Lennon go crazy. AND she's a horrible singer. Enjoy this 2:36 of pure bliss. Even if you have never heard Katy Perry's version you haven't heard Yoko's version. Don't say I didn't warn you.

See. I told you.
