Those, oddly, are the wrong lyrics. They're the lyrics to "Every Little Thing She Does Is Magic", which is quite the apt Prufrockian lyric.
Phew, that's a relief -- I'd realised it was completely the wrong song just after making the post, and for a moment I thought one title had morphed into the other in my head in the time it took me to switch tabs in Mozilla and Google for it... the right title on a page with the wrong song's lyrics makes me look at least a little bit less like a nitwit.

Anyway, the last wedding I was at had James's Just Like Fred Astaire, which I thought was a corking wedding song.
