Hi Ken,
Thank you for your post. I am not sure if it is Goin Down Slow, as I only heard it once on that show I mentioned, and heard only a few words. I do remember him saying "Mama" several times. Are you sure this might be it? Are you a fan of Ray Charles? It's really awful he has died, I loved alot of his music, he was truly gifted.
Anyway, tell me why you think this might be the song, did you see the show I am speaking of or are you simply familiar with all of his music?
Thank you.
