The session tapes are lost.

The movie version of 'One Track Heart' has the second "Ooo-wee, there'll be no turning back, ooo-wee I'm gonna stay on your track" line edited out.

Otis Blackwell's song 'Roustabout' 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 mono acetate.

The original master of 'It's Carnival Time' (HO-02) was deemed unsuitable by Paramount, so it was dubbed down to a backing track by removing Elvis' vocals. Elvis then recorded a new vocal overdub to this backing track on March 5.

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 was first released on Double Features and has Elvis singing "We gotta end" at the end of the song.

The movie version of 'There's A Brand New Day On The Horizon' taken from an acetate source with the following verse omitted, can be found on the bootleg Memphis Tennessee:-
I'm gonna tell ol' heartaches, pack his bags and go
I've decided that I don't want him hanging around no more
well don't you know I said everything's gonna be just fine
'cos the whole world's gonna be mine

The strange mix of the movie version of 'There's A Brand New Day On The Horizon' on the Elvis One release From Santa Monica Boulevard, Los Angeles, California - Part 2 (The Bootleg Series Vol. 24) appears to be lifted from the Blu-Ray release of Roustabout, where the "Score" can be found on a separate track of the Blu-Ray disc, and some of it without talking etc, which can be heard in the soundtrack of the movie.

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 recorded during the scoring sessions, and is spliced as follows:
0:00-1:17 = 0:00-1:17 of record version Take 15 (Start to last "Ying, ying")
1:18-1:35 = 1:21-1:38 of remake Take 21 (Guitar chords... "She did a triple summersault.." to "..nineteen forty nine")
1:36-2:19 = 1:34-2:17 of record version Take 15 ("Yeah... Let me tell you people..." to end)

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 for scene 74. Other songs with demo's submitted, but not used were 'I Never Had It So Good' and 'Carnival Of Dreams'. 'I Never Had It So Good' was replaced by 'One Track Heart' in the movie (scene 66), whereas 'Carnival Of Dreams' was dropped at the pre-selection stage.

Shout It Out was eventually recorded for the movie Frankie And 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.

An EPE auction in July / August 2010 however, has thrown up some questions regarding these sessions, as one of the lots had 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 reserved 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 planned to be recorded, but then 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. Another possibility is that production number "MO" was reserved for either 'Shout It Out' or 'I Never Had It So Good' to be recorded, but was not eventually used at all.

Update: At another EPE auction in 2016, more acetates from Roustabout were sold by Mary Lilley, daughter of Joseph Lilley, but there was no sign of an acetate of 'Shout It Out' by Elvis, recorded for the movie Roustabout!

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.
