My view is very similar to yours, but with a few differences:
• I picture
Dia do Bheatha as a solo, particularly for Muirgen, or a group number for the singers (since Tara wasn't involved in the recording of this song, but who knows, she could get in there
)
•
Silent Night and
Auld Lang Syne could transition from one song to the other since the former is played entirely in while the introduction and instrumental bridge of the latter are both played in the same key (Bb major)
• If
O Holy Night is performed, I'm assuming the arrangement used will be the 2020 version the group put up on YouTube
•
Carol of the Bells would be perfect as an opener and if there's no interval in recording the
Murphy's Mistletoe suite could be performed while the girls change their gowns (if possible)
• I would like to see a sort of sing-along medley (like what was done on the
MoC tour) nearing the end of each act; songs of a suitable nature would be
We Wish You a Merry Christmas,
Deck the Halls,
Feliz Navidad and
Sleigh Ride• Songs worth rearrangements for group numbers would be
White Christmas (acapella would be nice) and
I'll Be Home for Christmas• New songs I'd like to hear as group numbers would be
Let it Go (from
Frozen),
O Little Town of Bethlehem and
Believe (from
The Polar Express)
