Which band IS really America's Greatest (rock & roll band)?


When I consider my priorities for this category, I cannot come up with any other than CCR.

Their output as a band was short compared to others, yes..

When I say America's greatest rock & roll band, this = the output or even the basis on which a band formed, had in their DNA, America's roots! It doesn't even matter that we now know CCR formed in California, their DNA as a band transformed their birthplace but it more importantly brought forth the (soul) of get down and dirty) Rock & Roll in it's raw form!

HELL YEAH!

Spirit, a band from the late 60's to early 70's may not have been the greatest but were pretty darn good. The album Twelve Dreams of Dr. Sardonicus was a masterpiece. Hey, and how about Frank Zappa and the Mothers. That said I agree with nearly everyone. Too many good bands to really nail it down to one.
bdp24, thanks for that info on Traffic's lineup changes.  I need to pay more attention to the CD notes ( but the print is so tiny!).
Let’s start with North American Northern greats like Neil Young ,with or without Crosby stillsand Nash which ,were excellent , the Guess who another great band 
forgotton or overlooked, Steppenwolf in my opinion is still  timeless . And who can forget 
Santana , as well as Chicago. All special with their own styles and 
lets not forget the Doors , and Jim Hendrix experience !!
One more thing let’s not forget Steely Dan ,CCR, And the late great SRV,      Alman brothers, and Leonard Skinner.
