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!

I can't believe that Zappa and the Mother's, CSN or CSNY weren't mentioned. CCR, Tom Petty & The Heartbreakers, ZZ Top and Journey are awesome choices as well. 
geofkait - sorry i missed your mention
slaw - rock & roll has many genres, perhaps you should be more specific to how you define rock & roll.  it seems like you are stuck in your generation of rock - 'classic'.
Booker T & The MG's, the only band to work with both Otis Redding and Bob Dylan.
