I just read the other day that Elvis thought Roy Orbison had the greatest voice ever. I don’t know if he was including all the great opera singers or not.
Not sure Elvis heard the great opera singers. Maybe Grand Ole Opery.
Orbison, Carl Perkins, Jerry Lee Lewis and Elvis jammed one night at Sun Records. I think the CD came out awhile back and there was a broadway play, The Million Dollar Quartet.
Would liked to have been in the room.
