Yeah powderman,
I was born and raised in N.W. Louisiana and my daddy had a great bass voice and sang in a gospel quartet on KWKH radio in Shreveport for awhile. We went to alot of gospel singings at some churches that resembled alot of those shown with the YouTube of The old country church!!
We use to go to all of the professional quartet performances that we could make!
Some of the quartets we saw were "The Statesman", Stamps Baxter, the Stamps,
Florida Boys, Jordanaires( Use to sing with Elvis), Blackwood Brothers, etc!
Always enjoyed all of these shows.
