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 never recorded any vocals for Good,
Bad But Beautiful.
Elvis' session at Stax ended when his favourite
microphone was stolen, or misplaced. He tried
to continue and recorded Girl Of Mine,
but wasn't satisfied with the results and ended
the session.
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.
