Mahalia Jackson's In The Upper Room
 

Hello,

I have been trying to find the answer to this question for over 20 years.

On Mahalia Jackson's classic gospel recording: "In The Upper Room", does anyone know who the gentleman is who is singing bass on that recording?

If not, would anyone know where I can go to find the answer?

Thank you

According to the (admittedly minimal) research I've done, it may be one of these groups:

Supported by Mildred Falls, the Southern Harmonaires and the Melody Echoes (the two vocal groups are on different tracks)
