The undubbed masters on Our Memories Of Elvis weren't really the pure undubbed masters. They were the fully overdubbed or regular masters but with certain instruments and backing vocal channels removed or stripped down.

Elvis can be heard singing a couple of lines of 'Softly As I Leave You' before Take 2 of 'Loving Arms' on Essential Elvis Volume 5 and Elvis At Stax but it is edited in from before Take 2 of 'Promised Land' (December 15). Also edited in after Take 1 of 'If That Isn't Love' on the Venus bootleg Stax 73 - Unedited Masters is Elvis singing part of 'The Christmas Song' from the rehearsal of 'Thinking About You' (December 12).

An edited (1:48) version of 'She Wears My Ring', with omitted verse ("This tiny ring is a token of tender emotion.
An endless pool of love that's as deep as the ocean. She swears to wear it with eternal devotion. That's why I sing, because she wears my ring. She swears to wear it with eternal devotion, That's why I sing, because she wears my ring"), was released in 1987 on the BMG Ariola release The Definitive Love Album.

The live backing vocals were mixed out on Take 8 of 'She Wears My Ring' as presented on Essential Elvis Volume 5 - Rhythm And Country and FTD's classic album release of Good Times, but they are present on Elvis At Stax.

In March of 2007, Sony decided to go through all of Elvis' masters. They retransferred everything and remastered all tracks including repairing as many clicks, pops, bad edits and dropouts as they could. They have used these newly mastered recordings on their new releases since 2007 including budget soundtracks, Legacy releases, the 30 disc Complete Elvis Presley Masters collection and the Franklin Mint package.

All outtakes and masters used on the Sony 3xCD set Elvis At Stax have been completely remixed and remastered from scratch.

Thanks to Adrian V Stokes regarding the edited versions of songs on the BMG Ariola set of Definitive albums.
