I'm pretty confident that Mark Steyn is going to give this a slot on his Sinatra Century list, so I'll try to come back and update later on. Mark has some little, small problems with the lyrics which you can hear about here. I share those, but I'm even more bothered by "each fun time," an awkward, banal, earthbound phrase which strikes me as jarringly wrong for the notes they're paired with and for the tone of the song as a whole.
But "fun time" rhymes with "the one time," and I can't imagine the song without these poignant lines:
It well could be the one timeWith all its faults, I love it still, enough to rank it in my top thirty.
A hopeless little dream like that comes true
