Everyone’s favorite reason why the Beatles broke up, Yoko Ono, has never shied away from the weirder side of things. Last night on The Late Show with David Letterman was no different.

Yoko’s Plastic Ono Band, featuring her son Sean Lennon on guitar, teamed up with Oklahoma’s sultans of strange, The Flaming Lips, for a take on the rebellious “Cheshire Cat Cry.” Oh, and if you’re looking for Wayne Coyne, he’s the dude sitting in the black bag with the megaphone.

There are some pretty rad parts to this performance to be completely honest. The bass line is funky, and the Lips’ Steve Drozd shreds a double-neck Gibson with one of the necks ripped off. Yoko really goes off though. You’re going to have to watch the video yourself to find out.
