Actually, the "home" of the moon pie, or where it was invented is at a bakery in Chattanooga, TN in 1917. But, it is a "staple" found throughout most areas in Tennessee for sure and the south in general.
Here is a link from Bell Buckle's Chamber of Commerce site that gives the "most widely accepted" version as to how the town got its name.

thanks for asking, while I am well familiar with the town as it has the original of three college predatory schools - the "Webb Schools" in the US, (started in 1870); (the second is in California (1922) with separate girl's (1981), and the third here in Knoxville, TN (1955). I had never looked to see how it got its name. Interestingly, the original Webb School in Bell Buckle and the one in California were both founded as boarding schools but also take local day students. The one in Knoxville was never a boarding school and is the largest of the 3 schools. All three schools were founded by members of the Webb family. The one in Knoxville was founded by the grandson of the Webb who started the first one in Bell Buckle. While all named Webb School, and founded by members of the same family, they are different and distinct schools that operate independently of each other and are connected by "name" only. I always found that history interesting (my kids attended the one in Knoxville) and would like to get to Bell Buckle one day to see that area and school.
i look forward to hearing Randy's report on the show. I haven't previously heard anything about it.
