The Bridge School Benefit, Neil Young’s annual two-day all-star concert to raise funds for the special-needs school founded by his wife Pegi, kicked off at Mountain View, California’s Shoreline Amphitheatre yesterday. Fellow Desert Trip/Oldchella headliner Roger Waters performed a set of Pink Floyd songs backed by My Morning Jacket, and Young joined them onstage to close things out with a cover of Bob Dylan’s “Forever Young.” Watch below.

Earlier in the night Young joined My Morning Jacket on their cover of CSNY’s “Helpless.”
