 Between March 16 and 19 , 1971 , Dylan reserved three days at Blue Rock , a small studio in Greenwich Village to record with Leon Russell . These sessions resulted in " <unk> the River Flow " and a new recording of " When I <unk> My <unk> " . On November 4 , 1971 , Dylan recorded " George Jackson " , which he released a week later . For many , the single was a surprising return to protest material , mourning the killing of Black Panther George Jackson in San Quentin State Prison that year . Dylan contributed piano and harmony to Steve Goodman 's album , Somebody Else 's Troubles , under the pseudonym Robert <unk> Thomas in September 1972 .
