Rory is the first one that came to mind also.
I never got Rory Gallagher. My guitarist liked him, but I didn’t see anything in his songs.
Elvin Bishop had one song, as I recall largely carried by the incredible vocals of Mickey Thomas (Starship). He was in that difficult spot of not being a great guitarist himself, nor being a good enough singer OR songwriter to surround himself with a kick-butt band.
