I think it's hilarious that, because of the guitar solo, some people boycotted this song thinking they "sold out" and went "hard rock". C'mon, it ain't Helter Skelter or anything.
That said, I find the guitar solo one of the best parts of the song. <3
I adore this song, my words just do not do it justice. I only wish that Karen Carpenter had found happiness in her time here on Earth. She had an amazing gift - this song is just heartbreaking. (and yeah, it does have a really nifty guitar solo in the middle of it)
