The backup vocals were removed on Snowbird before
release.
Take 3 of Rags To Riches on 'Essential
Elvis Volume 4' is edited (mixed) to take out
Elvis' falsetto voice at the end of the take.
Take 3 is complete on FTD's 'Love Letters From
Elvis' Classic Album, but strangely it also contains
backup vocal overdubs on this release too. It
seems take 3 must have been considered to be the
Master originally, and was overdubbed, before
it was decided to use take 4 spliced with the
line "tell me you're mine ever more..."
from Take 3 as the Master.
