He's not rock and roll? So just WHAT is rock and roll?
Currently in the RR Hall of Fame are performers such as The Platters, The Drifters, the INKSPOTS!! and many many others who are, like Pat Boone, primarily ballad singers although Boone has done many rock and roll songs during his long career.
So, just WHAT is the criteria for the RR hall of Fame. I think the poster who mentioned his many Christian Albums may be on to something although Presley was also into Gospel.
