A few years back Bear Family Records issued two excellent series of albums called "Dim Lights, Thick Smoke and Hillbilly Music" and "Blowing The Fuse", which respectively feature country and rhythm and blues hits from way back when. Each series includes a separate album for each year in the 1950s (and in the case of "Blowing The Fuse", the late 1940s and early 1960s as well). Many of them are available on eMusic and I would recommend checking them out.
Here a couple of selections from each of the albums covering 1951. I am dedicating one of these songs to my dear friend Lord Roper, who celebrated a birthday last week. I'll let him choose which one.
"Little Red Rooster" - Margie Day
"Tend To Your Business" - James Wayne
"Chew Tobacco Rag" - Zeb Turner
"Too Old To Cut The Mustard" - The Carlisles
