Creedence helped get me through grade school. As for CCR not being "Southern", "Green River" is classic swamp rock. Obviously Fogerty and pals had Southern (not SoCal) musical influence. A classic band whose greatest hits CD helped get me through a drive from home on MD's Eastern Shore to Roanoke, VA in 2009.
I probably *heard* Charlie Daniels before finally hearing *of* him via "Devil Went Down to Georgia" in the summer of '79 (when I was fresh out of HS). IIRC he played on Bob Dylan's "Nashville Skyline" LP.
