'Yesterday', legend has it, had a working title of 'Scrambled Eggs'. Yeah, yeah, yeah...
Crazy innit. But true. It went
"Scrambled eggs, oh baby how I love your legs...." to help cement and establish the melody. Then it became a deep psycological subliminal treatise on the sudden and unexpected death of McCartney's mum when he was 14 and his reflection on how it all seemed so secure while she was still alive and his regret at some of the things he used to say to her. You know how kids can be.
Some that seemingly have no meaning(to me, anyway). Paperback Writer?

Yet I LOVE that tune.
Long before the Beats got a recording contract even, the first guy to turn some of them onto drugs and the odd sex orgy {written about in 'Polythene Pam'} was a poet {whom I'd better not name, in case he sues me !} who wanted to write paperbacks because in the very early 60s as things were changing, hardback books were seen as part of the old order whereas paperbacks were part of the '
new thing', where the money was. So the song was alluding to that but also were part of the Dylan/Jagger/ Townshend/ Davies/ Clark/Sloan inspired drift away from lovey dovey lyrics to subject matter that encompassed a wide variety of things and feelings and different modes of expression, real feelings that real people identified with. In the 4 years up to and including 1965, only 2 Beatle songs ( that they wrote) weren't about
luuuurrrrvvvve, ostensibly {'Think for yourself' and 'Nowhere man'}. Of the 16 they recorded in '66, 12 weren't.
Some lyrics are great. Some lyrics are functional. Some lyrics are rubbish. Whichever way, it matters not at all, as long as the overall song is good, memorable and means something
to the listener, in the same way it really doesn't matter if you can't hear the kick drum clearly or the bass clearly or catch the subtle beauty of the alternative guitar tuning........as long as the song is good, memorable and means something
to the listener.
It matters and it doesn't matter. It's the indefatiguable paradox !!
