Stevie Wonder just showed up on stage at the main keynote speech of Dreamforce, Salesforce’s big annual user conference.
He’s giving a live performance of some of the biggest hits, including “You’re the Sunshine of My Life” and “Signed Sealed Delivered.”
In fact, while singing “You’re the Sunshine of My Life,” Wonder slightly changed the lyrics to “Dreamforce is the sunshine of my life,” bringing some cheers from the crowd.
Dreamforce is known for having star musicians as guests. This year, Foo Fighters, The Killers, and John Legend are performing at the after party.
