Nick Dow said "It was quite interesting earlier on in this thread."
Is that before you started displaying your musical ignorance?
I only ever bought one Elvis recording ( Lovin' You" 10nch Lp 1957) And, I don't worshp him. But, I know a great rock singer when I hear one ( which is something you clearly can't do).
I also don't worship John Coltrane but it someone came on this forum and said that John Coltrane was a poor player who couldn't play in tune, then I'd have to take issue with that.
This whole matter could come down to ignorance... of not having a proper perspective of rock music and its history, its development, and its most important and influential figures.
John Lennon once said that " before Elvis there was nothing". Well, that statement certainly needs some - a lot - of clarification.
   But, to be fair to John, when Elvis first broke on to the UK scene in 1956, it was mind-blowing, and you had to be there to experience the sensation. ( and, again, all we knew of Elvis was THE VOICE)
UK teenagers had been fed a diet of middle-of-the-road pop by the BBC, and few youngsters had hardly any knowledge of the US's great black performers...apart from a few, like the very smooth Nat King Cole.
   But, one of the reasons that Elvis was such a good singer - apart, from all accounts - of having a fantastic "ear" - was that he had such eclectic listening habits.
   It's taken for granted that he listened to all the great blues and country singers, but he was also a huge fan of opera singer Mario Lanza and smooth crooner Dean Martin.
    This huge diverse listening experience produced a terrific, flexible, and original singer.
    When Elvis first visited Sun records in 1953, he was asked who - as a singer - he sounded like. Elvis, reputedly, replied " I don't sound like nobody". A double negative? Yes! But oh so true.
