Surprised there is no mention of George Jones yet..

For the 1950s stuff, 'Long Live King George' was issued on LP



but for something easier to find, a 1 disc chronicle of the Starday and early Mercury stuff only (to play by the rules of the OP kinda) then

The Definitive Collection 1955-1962


if ya dig GJ in general, then the 'Cup of Loneliness' comps...
