(Again, I don't know whether these are supposed to be the original arrangements as published? No name of an arranger is given so I am assuming that is the case).
"Always" is pretty. It's also, I don't know, to my ears almost a little sad or elegiac - there's certainly a tone of longing in there. (Or maybe it's just that I think it was used in the old (1974) version of The Great Gatsby or some movie like that, where the characters ultimately wind up unhappy). I'm probably seeing it through my own "lens" because the history of the song says Berlin wrote it as a wedding gift to his wife.
I also think it's interesting, while it's clearly meant to be a song involving ROMANTIC love, the chorus could exemplify other kinds:
With a love that's true... always
When the things you've planned
Need a helping hand
I will understand... always
That's when I'll be there... always
Not for just an hour
Not for just a day
Not for just a year
(And yes, Charles, before you ask: they have a version of Friday. Kind of done in a slow-jazz ballad style)
Edited to add: I think one of the reasons I like this kind of thing is the whole alternate-universe idea, that maybe there exists an alternate universe where swing jazz remained the dominant pop-music form or something, and life stayed generally more stylish than it is now....the fact that on the version of Friday they did, there's the comment "A little-known live recording from the Blue Note catalog" made me think of the alternate-universe angle.
