This is an interesting topic. I don't think that Elvis would have wanted to throw away his bond with tradition. Of course music changed during his life, but there are some roots which keep coming back; his love of religious music, country & western, (rhytm 'n) blues.. His style remained intact during his lifetime. After Elvis died, the world scene changed for the worse (AIDS, neo-conservatism, falling away of social structures, loss of cultural values & identity, new & violent wars). Most popular music of the decades after his passing away sounds plastic to me. Maybe he could have been active just with the music that was very dear to him; something like Johnny Cash did during the American sessions in the 90's and this particular decade. Although not suitable for commercial stations, this w?s great music! Other things I've been thinking about is co-operation with other musicians. I remember that the combination of Johnny Cash with Willie Nelson was worthwhile. I would have loved to hear him sing & perform with Roy Orbison, who died in the 80's. Anyway you look at it, it is speculation; but all in all I don't think Elvis would sell his soul for commercial appeal and I guess that he would have loved to stick to his roots. That doesn't mean that nothing changes. During the later part of his life Cash sounded very different compared to the material that was made during his starting out in the business, and so Elvis did change during his life, but the soul of these men was easy to recognize.
