The last production number used at the March sessions is "LO", which was for Wheels On My Heels, and the next number used is "NO", which is for the rhythm Track for Roustabout on this date. It is unknown what the missing "MO" production number could have been for but it is unlikely that it's for the Remake of Little Egypt as the master is Take 21, so it's assumed that the take numbering of "AO" continued from Take 16 to 21 for the Remake.

An EPE auction in July / August 2010 has thrown up some questions regarding these sessions, as one of the lots has some of Elvis' personally owned acetates of demo's presented to be used in this movie. Looking at the acetates, an interesting thought has emerged that the missing "Track MO" from these sessions could have been for Shout It Out. When you look at the acetate it has "USED" written on it, where the others - Carnival Of Dreams and I Never Had It So Good clearly has "Demo - Not Elvis" written on them. This indicates that Shout It Out could have actually been recorded, but not used in the movie 'Roustabout', but as the tapes are still missing from these March sessions apart from the masters and takes used for masters, there is no way of knowing exactly what was recorded.

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.
