Bob Crownover took over as the band's guitarist, but was replaced after a brief tenure by Bill Fiorio and later Steve Scorfina. Blair left a few months after Matt, with Gregg Philbin taking his place. The band also briefly added saxophonist Joe McCabe and trumpeter Marty Shepard to its lineup in 1968.
