The Stamps Quartet "FARTHER ALONG"
I didn't recognize some of the members on this video so I looked them up. This was evidently recorded in 1965 and the members were:
JD Sumner bass (1965-1980, 1988-1998)
Jimmy Blackwood baritone (1965-1969)
Roger McDuff lead (1964-1965)
Jim Hill tenor (1965-1968)
Chuck Ramsey piano (1965)
