Harsh comment kevin!!^^but I laughed.
I think the reason they put such a totally pants song on as b side to LIB was that self-mocking insinct that so many Brits have. Hey look guys, we've done something that everyone will think is really good, better mock ourselves before anyone else does!
LIB in my opinion (and after all that's what we're here for isn't it) is Paul not trying hard enough. He often does these songs that kind of mean something vague and big and deep , and are a bit universal, but they frustrate on close analysis because there's not a lot there after all. I often feel he's a clever kid who knocked out some homework that was only good because he's clever and gets away with it, rather than cos he worked at it. Not very well expressed for an opinion but I'm meant to be somewhere else at the mo, so am rushing this post!
I think the spiritual element is at least half there because of the churchy kind of musical feel. It's as much to do with the sound as the words. Oh and he had to namedrop in Mary as well. Tho my kids pop his pompous bubble by singing about Goldilocks and the 3 bears: Mother Bear she comforts me , they sing loudly to block out the real words, and carry on about porridge.
Maybe I'm Amazed, for example, shows that Paul could 'feel it' for real, he could express deep held feelings and he could combine lyric and music to powerful but specifically meaningful result. It's a song you can understand exactly what he means, whereas LIB is more general and vague.
I do like LIB though, specially when those big eyes look into mine and he sings it just for me.......
