Tape reel #2 was erased and reused on May 20, and tape reel #4 from this session is missing with no indication of what happened to it.
Reel #2 would have included some takes of 'On A Snowy Christmas Night' and the first six takes of 'Winter Wonderland'.
Reel #4 would have included outtakes of 'The First Noel' and 'The Wonderful World Of Christmas'.
An explanation why tape reel #4 may have been re-used or dumped, could be that Elvis may not have participated in the sessions and only overdubbed his voice. There would be no reason to keep the instrumental outtakes once the masters had been identified.

Jerry Carrigan didn't show up for this second night of recording, so Kenneth Buttrey was called in to replace him, although he wasn't present for the first session tonight, hence there are no drums present on 'I'll Be Home On Christmas Day'.

On the Today, Tomorrow And Forever box-set it wrongly lists Take 9 of 'I'll Be Home On Christmas Day' from this session as being released on there, when it is actually Take 9 from June 10.

Elvis sang an extra verse on the first few takes of 'I'll Be Home On Christmas Day' , and then that verse was omitted from Take 4 onwards, because Felton Jarvis said the song was too long. The master was then cut (Take 8) without that verse being included.

On June 10 Elvis re-recorded 'I'll Be Home On Christmas Day' again in a different tempo, but started off using the same (unused) verse. After Take 9 someone decided, again for whatever reason, to leave out that verse, and the (alternate) master was cut without this verse. The extra verse is as follows:-

It's been so long since I've seen little John, Michelle, Christine and Karen;
(I) almost forgot all the presents that I bought, a purse for little sister to carry
(If) I could set aside my pride, I'd just be on my way,
I'd be on that (catch that) train tomorrow, I'll be home on Christmas Day

'The Lord's Prayer' on Essential Elvis Volume 4 has the musicians way back in the mix and has dialogue edited in from before Take 6 of 'A Thing Called Love' (May 19), along with a line from 'You Better Run' edited in.

'On A Snowy Christmas Night' on the bootleg O Come All Ye Faithful is probably just the left channel only (centred) of a stereo acetate of the fully overdubbed master. By eliminating the right channel on the same track on Christmas Peace I was able to get the exact same results. This is possible because backing vocals (and occasionally strings) tend to be panned 100% right on the original mixes from these sessions, so you can often eliminate them by cutting out the right channel, with no discernable bleed.

A fake extended version of 'Don't Think Twice, It's All Right' can be found on the old bootleg LP box Behind Closed Doors and more recently a longer faked version can be found on the Madison bootleg Don't Think Twice.

It is unknown who is singing backup vocals on 'O' Come, All Ye Faithful' as there was no vocal group present during this session. It is possible that it is Charlie Hodge and/or Red West, along with any other of Elvis' friends who were present.

Take 2 of 'O Come All Ye Faithful' was first released in 1982 on Memories Of Christmas at which point it was issued a different serial number (MWA5 9085) to the master (APA4 1270). This was because it was spliced with Take 1.

The undubbed master of 'O Come All Ye Faithful' on the 4xCD box-set Elvis Back In Nashville is presented without backing vocals, although they can be heard faintly, bleeding through Elvis' microphone.

A fake "vocal only" version of 'The Wonderful World Of Christmas' has been doing the rounds amongst collectors, but this is just one channel removed from a binaural mix, and then centred. This gives the effect of having no backing singers or musicians present.

The re-recordings of 'Winter Wonderland', 'O Come, All Ye Faithful' and 'The First Noel' can found on the 2017 album Elvis: Christmas With The Royal Philharmonic Orchestra, which contained Elvis' original vocals but with new backings by The Royal Philharmonic Orchestra.

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.

All outtakes and undubbed masters used on the Sony 4xCD set Elvis Back In Nashville have been completely remixed and remastered from scratch.

Thanks to Michael Schemies for pointing out the mistake regarding 'I'll Be Home On Christmas Day' on Today, Tomorrow And Forever.

Thanks to Colin Bryant for pointing out the European pressing of Christmas Duets containing the duet with Hanna Pakarinen from Finland.
