Thank you for the reply. Yes, your suggestion of Bonnie Pointer makes a lot of sense and may also explain who some of the others are. I'll have to refresh my memory on the vocal nuances of The Pointer Sisters and do a comparison to confirm. I suspect you are right, though.
Do you recall if they recorded "You Got Me Hummin" on any of those Blue Thumb LPs?
Also curious for functionality sake-- did you mean to post your reply in our original thread or was this new one intentionally out of that thread?
Thanks again, MrBB
