I watched Terry and McGhee in Toronto in the later 1960s at a gig at the Riverboat. At the end of the set, the limping McGhee, with a boot's sole two or three inches higher than the other, led the blind Terry off the set, together playing and singing "Walk On." Unfortunate that they had a tempestuous personal relationship with respect to the economics of their music, which would prematurely curtail their co-performances.
These are photos from concerts where Sonny Terry and Brownie McGhee played, so they may be of other bands that played the concert as well.
