Yoko Ono’s odd “cover” of Katy Perry’s ‘Firework’

A clip of Yoko Ono performing her own rendition of Katy Perry's tune "Firework" back in June has recently gone viral, but sadly, it might not be real.

However, that shouldn't stop you from enjoying this interesting interpretation of the track.

With almost 300,000 hits on YouTube, viewers seem quite confused about Ono's "performance" and have left comments like, "What exactly was she doing or think she was doing there?"

Wrote another: "Is she in pain? orgasmic? Or is she having a seizure? I really can't tell."

NME points out that the footage of the 79-year-old activist at what looks like an art gallery event is edited together with Perry's song and as proof, more covers like it exist on the same YouTube channel.

After exploring the various videos posted by YouTube user Kroiker McGuire, we found the same scenes of Ono "singing" over tunes such as Adele's "Someone Like You," Taio Cruz's "Dynamite," Lady Gaga's "Bad Romance" and even "The Star-Spangled Banner."

We feel that the emotion expressed in Ono's delivery goes particularly well with the Adele version of the mash-up and if it were real, could have been considered performance art.

Which rendition do you think works best?
