In June 2008, a Skip Spence tribute concert was held in Santa Cruz. The concert featured Spence's son Omar, who has sung with various configurations of Moby Grape in recent years. Omar Spence, singing his father's songs, was backed by the Santa Cruz White Album Ensemble, with Dale Ockerman and Tiran Porter, both formerly of the Doobie Brothers, and both of whom have played with various members of Moby Grape in several bands over the past three decades. Don Stevenson (an original Moby Grape member) also performed. Keith Graves of Quicksilver Messenger Service played drums.
