It’s a Rock and Roll Hall of Fame tradition to have a jam session with inductees new and old at the end of the ceremony. This year was no different: After the Red Hot Chili Peppers‘ own three-song set late Saturday night, frontman Anthony Kiedis encouraged others to join them onstage.

Naturally, one of the first to rise to the occasion was funk legend George Clinton, a long-time RHCP pal who earned effusive praise from bassist Flea and Kiedis in their acceptance speeches. Soon after, Guns N’ Roses guitarist Slash, Faces / Rolling Stones guitarist Ronnie Wood and Small Faces/Faces drummer Kenney Jones and Green Day’s Billie Joe Armstrong joined the fray.

The supergroup launched into — what else? — ‘Higher Ground,’ the Stevie Wonder classic RHCP made their own on 1989’s ‘Mother’s Milk.’

The extended version of the song never careened out of control — but it did exhibit hallmarks of the exuberant chaos for which all of the bands onstage are known.
