CCR was the first band to outsell The Beatles in America. Most of their songs were standard length but they occasionally stretched out a bit as with "Ramble Tamble" and "Keep On Chooglin". The latter has a harmonica solo you might like to hear. It starts around 2:15 and ends around 4:00 if you don't care to sit through the rest.
Raise your goblet of rock!

On another note (trying for a cute analogy) I recently bought an old used receiver. My good one has a bad capacitor in the output amp that produces a horrendous 60Hz buzz. The one I just bought has the right outputs to finally let me digitize the roughly 150+ LPs I have. Now I just need to find the time.

That is indeed a marvelous harmonica solo. Thanks.
I have a ton of 33s too... probably close to a couple 1000. My mother bought them like crazy from yard sales for pennies, but she was pretty indiscriminate, so I have Perry Como, West Side Story, Jimi Hendrix, Country Joe and Fish.... no focus whatsoever. Most of the ones I've tried are at least playable.
I'm more of a folkie than a rocker even though at certain points the genres sometime blend. But I prefer rock from the classical eras - late 1950s through the 1970s. Possibly my favorite group is CCR, although preferences often change day to day and can be mood-dependent.
So, in honor of John Fogarty, here's Zack Brown with Dave Grohl and Bruce Springsteen doing a great cover of "Fortunate One."
