"Mystery Train", by Elvis Presley. Are you meaning to tell me that this never got into the UK top 40? A remarkable failure of record company savvy, if true. Or were there copyright issues?
So, if the lineage of music-related megastardom goes, Frank Sinatra -> Elvis Presley -> Michael Jackson, and we are living in a megastar-devoid moment, who, assuming nature's usual abhorrence of vacuums, could possibly fill that hole? (And, on the evidence of the latter two, (why) would anyone want to?)
