The rock & roller and one of his idols share a guitar on “Everyday I Have The Blues” at the Montreux Jazz Festival, 1972.
According to a poster on Charlie Gillett’s music forum (where I found this clip), Walker’s own set the previous day was recorded and released on an LP, Fly Walker Airlines which was to be his last album. Walker was the first bluesman recorded playing electric guitar and died in 1975.
