Hey Don,
It sounds like you're looking for songs that can be played instrumental, just guitar, no singing, no backing. Melody and chords all in one. Is that right?
This one is pretty advanced, but Anders did a version of Sting's "Fields of Gold" which is pretty cool!

Otherwise, I am sure we have some other things like that. It's just that it tends to be on the more advanced side of the spectrum, since you're basically doing two things at once. (Melody and chords).
Anders gets into that stuff a lot in his Acoustic Course. It tends to be on the sort of "Ragtime" side but it's all good stuff!
-Carl.
