Have always read that Elvis was not too fond of "Burning Love" but can't understand why. Anyone have any insight? It's a KILLER track, the band was hot, everything came together. It's hard to imagine that this song was held out of the #1 spot here in the U.S. by the Chuck Berry novelty tune "My Dingaling". With some rare exceptions, most notably Promised Land, Elvis never seemed to rock this hard in the studio again.
If he couldn't get new "Rock" material in the 70's, why do you think he didn't record more covers of harder edged material from other performers? I always thought John Fogerty/CCR wrote stuff that suited Elvis to a "T". Elvis' version of Proud Mary from the On Stage 1970 Lp ROCKS!!!!
There seemed to be an untapped pool of material from which to choose, even if the stuff had been previously covered/written by other artists. Elvis could have done wonders on almost any Roy Orbison, which all seem like Roy wrote them for Elvis to record anyway, or Everly Brothers tune. For an idea of how Elvis handled Everly Brothers material, check out "Let It Be Me", again from the On Stage Lp.
Elvis had made such an impact on the 2nd generation of Rockers, that I feel confident any of them, including any of the Beatles, would have jumped at the chance to work with/record with/write for Elvis.
