The session tapes are lost.

Otis Blackwell's song Roustabout (which is referred to as "No.2") was the only song of his that the songwriter knew was recorded. It was eventually released on 'Second To None' as I'm A Roustabout, where it was taken from Otis Blackwell's own acetate.

The movie version of It's Carnival Time is an unknown vocal overdub take. That same version appears twice in movie, one with instrumental overdubs of the intro and one edited version.

The book "Inside Roustabout" shows a music sheet for the song Carny Town, and this has an extra verse that may have been recorded, and then edited out of the final master. The original version of Carny Town that appeared on the 'Roustabout' LP is faded. The complete version can be found on 'Double Features' and has Elvis singing "We gotta end" at the end of the song.

An edited version of There's A Brand New Day On The Horizon taken from an acetate source, can be found on the bootleg "Memphis Tennessee".

According to an interview with Sonny West:- "Elvis and John Rich (director) had their problems. Elvis wanted to do a song with the Jordanaires callled "Wheels On My Heels", but Rich argued that since Elvis was suppose to sing the tune when he was alone on his bike, the backup singers would be out of place. Elvis won that one, but Rich got him back by making him do take after take when Elvis had a temperature. The master of Wheels On My Heels does not contain any backing vocals by The Jordanaires, but it could be possible that earlier takes did include them.

The movie version of Little Egypt is a composite of the record version and the remake, but also has extra overdubs that were presumably recorded on the movie set, and is spliced as follows:-

0:00-1:17 of record version Take 15
1:21-1:38 of remake Take 21
1:33-2:19 of record version Take 15

The song Shout It Out was originally submitted to be used for the movie, but was eventually dropped in favour of Hard Knocks being used instead. Other songs with demo's submitted, but not used were I Never Had It So Good and Carnival Of Dreams.

Shout It Out was eventually recorded for the movie 'Frankie & Johnny' in 1965.

The last production number used at these 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 April 29. 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.
