Lumdeloo, if we used Glen's Autobiography as a general source, it would rule out much of the "Country" genre; I believe he stated that he doesn't believe himself to be a Country performer. There are quotes on the back of certain CD reissues where Glen dismisses the Country genre as well. As a musician myself, I'd argue most of his output was Folk; there was no sixties Pop sound, IMO. You could easily label the albums as Pop, but sixties pop versus seventies pop versus eighties pop versus nineties pop are all different. For instance, one may consider Hall and Oates "Rich Girl" to be a Pop song, but the Bigger Than Both of Us album has several genres; mostly Rock. So, I'll take some free time to compile all the Glen quotes/info I can, when I can, and try to work with you to come to a decision. I must say, though, most sources will work in your favor, despite my disagreement with them. Hopefully this can be a fun collaborative project.
