Bob Dylan is mourning his friend Garth Hudson. On Monday, the musician posted a tribute to the Band keyboardist on X, remembering him as the group’s “driving force.”

The longtime keyboardist and organist of The Band, Garth Hudson passed away in January at the age of 87.

Bob Dylan has returned to his favorite social-media cesspool of choice, X, not to review a trio of SNL curveballs from a certain young admirer but to instead memorialize a recently deceased friend and collaborator.
