I have a great recording Lovesick Blues by Emmett Miller (with yodels) on Okeh on June 12 1928, accompanied by his Georgia Crackers (which included Tommy Dorsey, Jimmy Dorsey, Eddie Lang, and Leo McConville).

Ernest Tubb is my favorite country singer, of course, but for me Hank Locklin's Fraulein seems the quintessential country melody. Although, Great Speckled Bird, as Kendall suggests, and You Win Again, by Hank Williams, are close, in my opinion.
