I've learned that there is something called "Morris Dancing," but I still don't know what it is.

I've learned that different countries had entirely different and separate "folk revivals" about 40-some-odd years ago.

I've learned that many people around the world who profess an interest in folk music have difficulty agreeing on much of anything, BUT. . . most of them are very articulate writers of opinionated prose. And I thought I was the only one!
