Of all the gospel groups I heard there, none were black, and that was my loss, one I didn't realize the full impact of until I heard Albertina Walker sing Until Then at Christ Universal Temple in Chicago. For years I searched for a copy of the song with no results. I did obtain a number of Ms. Walker's albums, but none of them included Until Then.
A couple of years into my search, I found a different version of the song by Charles Johnson and the Revivers. I fell in love with that one also, and have listened to it more times that you would believe.
Then a few weeks ago, I found it on YouTube and since then I and my neighbors and quite a few pedestrians passing our house have listened to it a number of times.
This evening was a running off-night for me, so while Christina ran, I cranked up the volume and played Charles Johnson yet again. As the song ended, I had an inspiration - search YouTube for Albertina's version and you guessed it, I found it.
Here are both for your listening pleasure:
