Yes, Cowboy Copas and Hawkshaw Hawkins are legends too.
It took some years before discovering them, but they both made some great records.

Hawkshaw Hawkins is my favourite of the two.
Hawkins recorded many great sides in the early 1960s which I love.
"You Know Me Much Too Well" (1960), "Big Ole Heartache" (1961), "Twenty Miles from Shore" (1961) and "Darkness on the Face of the Earth" (Willie Nelson)/I Can't Seem to Say Goodbye (1962) are a few favourites.

I haven't listened much to Cowboy Copas but he was a great guitar player besides a great singer.
If it is he who plays guitar on "Alabam".
I also like "Flat Top Guitar Blues" & "Sold the Farm".
