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.
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.
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.
