The master of 'A Big Hunk O' Love' is primarily Take 3, but with the first instrumental break spliced in from Take 4.

Since the release of the 50s Box, it seems more common to have Take 3 of 'A Big Hunk O' Love' rather than the original spliced master, and it has since appeared on Elvis 30 Number One Hits and the Japanese 24 Bit mastered CD Elvis' Golden Records Volume 2 among others. On the original RCA CD release of Elvis' Golden Records Volume 2 however, we get the original spliced master. This may be because in the original session logs Take 3 is listed as master and they may have gone back to the original tapes for these more recent releases, and Take 3 will have been on the tape reel instead of the spliced master. A good transfer of the original spliced master of 'A Big Hunk O' Lov'e can be found on the Japanese 24 Bit mastered CD The Complete Single Collection (CD2), All Time Greatest Hits and FTD's 50 Million Elvis Fans Can't Be Wrong and also remastered on Sony's Complete Masters Collection and the Franklin Mint package.

There was no satisfactory master take of 'Ain't That Loving You Bab'y at this session, and it is listed as such in the session logs. Take 4, however, was eventually released in 1964 as a single so would have been considered to be the master from then on.

In 1984 a new digital master (fast version) of 'Ain't That Loving You Baby' was made by RCA and issued with a new matrix number (PPA5 2672), that was subsequently used on the album Reconsider Baby.

Elvis Sound Magazine web site has an estimation of how thefast version is spliced - Thanks to Jim Berkeley:

0:00.0-0:10.8 = Take 09 ("I could ride around the world" to first "Ain't that")
0:10.8-0:17.9 = Take 10 (first "loving you baby, ain't that loving you baby, ain't that loving you baby")
0:17.9-0:21.3 = Take 11 (first "Ain't that loving you so, oh oh oh, oh oh oh")
0:21.3-0:41.0 = Take 11 ("I could meet a hundred girls" to second "Ain't that loving you so, oh oh oh, oh oh oh" - drum bridge #1)
0:41.0-0:46.5 = Take 08 (drum bridge #1 and guitar bridge #1)
0:46.5-0:49.3 = Take 11 (guitar bridge #1)
0:49.3-0:52.0 = Take 08 (guitar bridge #1)
0:52.0-1:14.1 = Take 11 (guitar bridge #1 - "If you gave me nine lives like an alley cat" to third "Ain't that loving you so, oh oh oh, oh oh oh" - drum bridge #2)
1:14.1-1:22.1 = Take 08 (drum bridge #2 and guitar bridge #2)
1:22.1-1:27.3 = Take 10 (guitar bridge #1)
1:27.3-1:33.0 = Take 11 ("I'm putting on my coat" to third "Before the sun goes down")
1:33.0-2:00.6 = Take 11 (third "Ain't that loving you baby, ain't that loving you baby, ain't that loving you baby, ain't that loving you so, oh oh oh, oh oh oh" - drum bridge #2 and guitar bridge #2)
2:00.6-2:13.5 = Take 11 ("I could ride around the world" to first "Ain't that loving you baby, ain't that loving you baby, ain't that loving you baby")
2:13.5-2:17.0 = Take 11 (fourth "Ain't that loving you so, oh oh oh, oh oh oh")
2:17.0-2:22.5 = Take 11 (fourth "Ain't that loving you baby, ain't that loving you so, oh oh oh, oh oh oh")
2:22.5-2:27.3 = Take 11 (fourth "Ain't that loving you baby, ain't that loving you so, oh oh oh, oh oh oh")
2:27.3-2:32.0 = Take 01 (ending speeded up by 5%)

Take 8 of '(Now And Then There's ) A Fool Such As 'I was used on Elvis 30 Number One Hits instead of the master (Take 9)

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.
