George Grantham (born January 20, 1947 in Cordell, Oklahoma) is an American drummer and vocalist best known for his work with pioneering country rock band Poco. Grantham and pedal steel guitarist Rusty Young were members of the Denver-based psychedelic rock act Boenzee Cryque when Young left the band in mid-1968 for Los Angeles. There, Young fell in with Buffalo Springfield members Richie Furay and Jim Messina as they wrapped up that band's final album.
