New Riders of the Purple Sage opened its vaults last week and dug up a vintage video of “School Days” featuring Jerry Garcia. The video, released on December 23rd, comes from the band’s performance on December 15th, 1973 at Winterland Arena in San Francisco, CA.

Though Garcia had officially left NRPS’s pedal steel chair in 1971 as the Grateful Dead climbed to greater and greater success, that didn’t stop the guitarist from dropping by during a hometown show. The lineup for the country-rock forefathers—which has been something of a revolving door throughout its 50-year tenure—at this point included John Dawson (guitar, vocals), David Nelson (guitar, vocals), Buddy Cage (pedal steel), Dave Torbert (bass, vocals), and Spencer Dryden (drums).

The Chuck Berry cover hears Torbert taking lead vocals on what would prove his final show with the group, per Rather than the guest of honor, it is Nelson who provides the call-and-response guitar leads to Torbert’s vocals. Garcia gets his moment in the spotlight eventually, sporting a Fender Telecaster for a change. This show came as the second of a two-night run at Bill Graham‘s Winterland, featuring opening support from Jesse Colin Young and Linda Ronstadt.

Watch New Riders of the Purple Sage perform Chuck Berry’s “School Days” with Jerry Garcia at Winterland in 1973.
