A very rare acetate has popped up on eBay. The songs are: Your Cheatin' Heart; Crying In The Chapel; Tell Me Why; When It Rains It Really Pours; Angel; Sound Advice; A Whistling Tune; You'll Be Gone; In My Way; Forget Me Never; Tomorrow Night; For The Millionth And The Last Time. The sound sample of 1954's "Tomorrow Night" sounds undubbed, which means this pressing was done prior to the March 18, 1965 overdub session in Nashville - it also sounds as if You'll Be Gone is an alternate take.
According to experts on the FECC Forum, it seems to be an early pressing of the Elvis For Everyone LP containing all unreleased tunes that RCA had in the can as of the middle of 1962, since You'll be Gone is the latest recording on the acetate. However, it was strange that Angel and A Whistling Tune would included since it had already been inlcuded on the Follow That Dream EP and Kid Galahad, respectively. The signatures are fake, unfortunately. If you're interested: here's the link
