WATCH: Paul McCartney Jams 'Helter Skelter' With Muse

Rock band Muse was joined on stage Tuesday night by none other than Beatles legend Paul McCartney for a cover of “Helter Skelter.”

The rock stars jammed the 1968 Beatles track as supergroup Dr. Pepper’s Jaded Hearts Club Band, which also includes Chris Cester of Jet.

“Just did Macca with Macca,” Muse's Matt Bellamy captioned a video clip, in which he is seen playing bass, on Instagram.

McCartney, 75, also sang along as the band performed the 1963 Beatles classic “I Saw Her Standing There.”

It all went down at the launch of a new fashion line from McCartney’s daughter, designer Stella McCartney, in Los Angeles.
