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 the March sessions
was "LO", which was for 'Wheels On
My Heels', and the next number used is "NO",
which was 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.
