I've recently started learning If I Can't Speak For Jesus.. a song recorded by the Five Blind Boys. I'm not a tenor, and NOBODY can match the original lead in fervor or emotion. The other four are mostly just hmmmmming in the background. Which is the usual arrangement for the Five Blind Boys of Alabama. When I approach the song, I hear it as a blues. I originally learned to fingerpick from Dave Van Ronk, so the song naturally slides into a blues flavor. With no noticeable change in phrasing or feel. Of all the black gospel quartets, the Five Blind Boys seem to be closest in feel to the blues. I have a CD of gospel by Otis Clay, a fine rhythm and blues singer, and it all flows naturally. My buddy Frank said that the only difference between the old jook joint jump tunes and the Sunday morning gospel is that on Saturday night, you can shake your hips from side to side, and on Sunday morning, you move them up and down.
