Elvis and The Band

I just saw an advanc screening of Baz Luhrman's new imax film 'EPiC Elvis Presley in Concert' and it was great. At one point, Elvis sings "I shall be released." Which got me wondering ... I don't recall what the members of the Band had to say about Elvis, if anything, as far as him being an influence on them, or what they thought of him in general.Does anybody recall?
