All songs on the Double Features release have
left and right channels reversed.
The master of 'Clambake' on Double Features has a noticable drum beat missing at the end of
the song.
Take 11 of 'Clambake' that appeared on Silver
Screen Stereo is actually Take 3B. The listing
mistake probably arose due to the editing on that
release, and the Take 12 announcement, as Take
1 of the reprise follows straight after this.
The reprise must have been recorded straight
after the main version of 'Clambake', and
Felton mistakingly called Take 12, before the
engineer correctly announced Take 1.
In the 'In & Outtakes' section of the booklet
with FTD's Clambake extended soundtrack, it's indicated
that Ray Walker and Elvis' vocal overdubs were
done separately for 'Who Needs Money?', along
with a 'cue' vocal overdub and an 'insert' vocal
overdub. My guess is that the 'cue' vocal overdub
of 'Who Needs Money?' is the part that is
on the record version but not the movie version
(1:36 - 2:01 of record version), and the 'insert'
vocal overdub (done on March 6) is Elvis' re-recorded
'ending'.
Elvis did a vocal repair on 'Confidence'
on March 6, and this was the vocal used for the
movie version. The movie version however,
had children singing along, probably recorded
on the movie set.
The record version of 'Confidence' had
a re-recorded first verse (probably recorded sometime
between August
17 and September 11), and also had female
vocals overdubbed on September
19.
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.
