Bill S. Preston, Esq. and Theodore "Ted" Logan are back for Bill & Ted Face the Music, which means their band Wyld Stallyns rides again.

To celebrate the first day of filming, Bill actor Alex Winter shared a photo from the set of the third Bill & Ted movie. In it, his back faces the camera. He wears a teal shirt with the "Wyld Stallyns" logo across the back in blue print.
