Thomas, thank you very much for explaining those terms, knowing their meaning enhances the experience.
This song, as sung by John Lennon, is pretty good; but as sung by Fionna Apple is outrageously lush and supreme. There's one part in her performance - where she begins to sing the lines
"Limitless undying love which shines around me like a million suns" - that is one of the greatest vocal performances that I have ever heard in my life. As sung by Ms. Apple, this is one of my favourite songs of all time.
Also, I should point out that the song was originally created for the soundtrack of the movie
Pleasantville.
