Yes, Elvis' version of the classic 'Fever' is a musical masterpiece in itself. I too first heard The King's live version via the 'Aloha' show but this was on a tape recording I had received just after Elvis died. Soon after I got hold of a copy of the UK Double album 'Elvis' 40 Greatest' and became an immediate fan of his studio version from 1960. Then, later on, I bought the original LP that it was taken from - 'Elvis Is Back!'
Have you purchased the new upgraded CD of 'E.I.B.' from the Follow That Dream Label? There's some great out-takes of the song on this one!
