I liked Creedence in '69 and '70, when their sound was fresh and new. John Fogerty's voice was unique then, even though fans had a bit of a letdown when it came out that none of the band members came from anywhere
near a bayou or swamp. That was then, this is now.
Although I still like to hear some of their songs...
Fortunate Son comes immediately to mind, as does their cover of
Good Golly, Miss Molly.
Like a lot of the sixties and early seventies bands, their music sounds dated to me now. And unlike a lot of other bands of that era, I don't particularly associate CCR with memorably good times. They were just background music to a few years of my life. Their music lost any relevancy it might have had for me once the new music of the eighties took hold...that and the rockabilly revival almost totally eclipsed my previous musical likes.
I don't listen to the radio much (if at all) now...preferring to use Bluetooth in the car and listen to the music I've loaded into my iPhone. When I do happen to have the radio on and CCR comes on, my first thought is usually something along the lines of why-am-I-listening-to-this-
now?
Creedence Clearwater Revival? Gone, but not
completely forgotten, I guess.
Could happen to anyone
