W.W.J.D? (What Would Jerry Do?) originally formed to play a single memorial show for Robert Hunter, in October of 2019 at Zoetropolis in Lancaster, PA. The sold-out tribute received an overwhelmingly positive response, leaving many asking for more. In January 2020, the band began a once/monthly residency at Zoetropolis, known as "Steal Your Sunday." As word spread, and their reputation grew, W.W.J.D? started expanding into surrounding markets. The music of W.W.J.D? primarily features the music of The Grateful Dead and Jerry Garcia Band, with the occasional curveball thrown in.

The band's lineup involves a bit of rotation from time to time. Still, the core of the group is comprised of Matt Hostetter (The Quiet Riders) on guitar/vocals, Charlie Muench (Philly Nelson/The Stray Birds) on bass, Josh Kanusky (David Bromberg Band/The Quiet Riders) on drums, and Jake Joyce (Jake Joyce Band/Rascal Revival) on guitar/vocals.
