Hoping more skillful researchers than am I can help me find information about a Gospel Quartet, the National Harmonizers that recorded "Death Comes Knocking" in Detroit, 1954, on Fortune Records.

Can't find anything about them other than the one recording on Youtube.   


Death Comes Knocking - National Harmonizers

The members were James Williams, Samuel Scott, Elle Canada and BJ Hardy. I have no idea if they were a Michigan group or not. Have searched all their names and can't find anything, and can find no references to
"National Harmonizers" aside from this one recording.

Any help or additional information appreciated.
