As the Shadows of Knight's short-lived run through 1966 and mid-1967 came to an end, McGeorge accepted a surprising invitation from H.P. Lovecraft's leader, George Edwards (aka Ethan Kenning), to join that band on bass. With another difficult career decision behind him, McGeorge made the transition to not only a new group and a new genre, but to a new instrument as well. With only a few days to learn his new band's songs and bass lines, he appeared on their notable first album of the same name. McGeorge again succeeded in adding a unique dimension to this somewhat quirky band and its thematic repertoire.
