But it's too late, baby, it's too lateThere's internal rhyme in the third line ("inside," "died," and "hide") which I hadn't noticed, but it doesn't end there. The "I" in "I can't hide" has the same vowel sound as those "-ide"s. So there's that internal rhyme, but with the "I" there's also assonance, resulting in four mellifluous elements in the line: "inside," "died," "I," and "hide."
Though we really did try to make it
Something inside has died, and I can't hide
And I just can't fake it
Listening to the Tapestry album so I could write this post, I also noticed that there are backing vocals ("We can't make it") after the line "Though we really did try to make it." I don't think I'd really paid attention to those either, but that's the sort of thing I'm always excited to find: instances where the backing vocals are sort of duplicitous when compared to the main vocals. I'm not sure I would describe the relationship between the main and backing vocals here as duplicitous, but they do have slightly different perspectives. The main vocals seem sort of regretful that a relationship is ending, but the backing vocals seem more adamant that it can't work.
