Hey, C-flat! Funny thing is (and a topic for a thread, I guess) the bass "words" for rhythm and blues groups are very different than those for black gospel quartets. That's true, even though most of the classic black R & B groups came out of black churches. The bass lines in black gospel are very limited... either ooh, aah, or dumm.
No dip dips, rat-a-tattas or Shoobee-doobies. I must admit, because of my love for R & B (it was never referred to as doo=wop when it was popular,) I hear black gospel with a more colored pallate of bass words.

Didn't know you liked the old rhythm and blues.... It is a MAJOR love of mine, and I have a ton of recordings.
