Back in 2006, P.O.D. brought their hit “Goodbye For Now” to The Tonight Show, delivering an electrifying performance that fans remember to this day. But the real surprise? A young Katy Perry joined the band onstage, lending her vocals to the powerful track.

It’s a fascinating early moment in her career, adding an unexpected layer to P.O.D.’s already impactful performance.
