Elvis overdubbed the "Guitar Back Beat" and "Piano" background himself.

On the CD version of 'Worldwide 50 Gold Award Hits Volume 1' the Undubbed Master of Wear My Ring Around Your Neck was used, however, on the original 4LP set of 'Worldwide 50 Gold Award Hits Volume 1' the Overdubbed Master was used.

'Sessions III' incorrectly lists the Undubbed Master of Wear My Ring Around Your Neck as being released on 'Gold Records Volume 2' when it was the Overdubbed Master used on the original release of that album. The Undubbed Master actually first appeard on the 1985 RCA CD (10 track U.S. version) of 'Gold Records Volume 2' however, and it's first commercial (International) release was the 1987 compilation 'All Time Greatest Hits'.

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.
