#never know

First, this song feels heavily inspired by past musical Beatle business (tape loops, close harmonies, mellotron, electric piano, recorder à la Fool on the Hill) but the lyrics feel placed in the early 70s timeline of the breakup and escape to Scotland. Let’s take a look:

I want to be the one | That's rooting for you | Lying in the sun again | I want to feel your touch | The things that you do | Have always meant so much to me

I don’t think he’s literally talking about lying in the sun (although he’s likely using a double meaning here), I read this as John being the sun. ☀️ The charismatic genius he bet his life on. When all is right with the world, he’s typically basking in John’s glow. Almost all of John’s attention and warmth, creatively and personally, has been on Paul up to this point. But now the sun shines on Yoko and he’s longing to be the partner who is John’s main support and focus again.

I want some love and peace | We need it right now | Your wonders never cease to be

At this point in time, John and Yoko are heavily engaged in their Peace activities. And Paul seems to be saying: okay, so you’re promoting a facade of love and peace to the world but, to me, you’re attacking my whole existence. Don’t I deserve love and peace right now too?

I love you, but you know | My heart is breaking over you | When you got me on the run | My body's shaking, oh, oh, oh | My mind is black and blue | I love you, but I never know

Here’s where this song took at turn that, in my mind, made me more certain that this is a “John Song.” The lyric “you got me on the run” alludes to his and Linda’s escape to Scotland to spin out, mourn, and heal in private. And the reason I think that is because of the line “my body’s shaking,” which instantly reminded me of the quote below from the book Wings: the Story of a Band on the Run

And this interview from All You Need Is Love: The Beatles in Their Own Words calls out shaking a little later in the timeline.

I'm gonna take the time | To prove that I care | Don't mind as long as I'm with you | I've got to make you see | I'll always be there | I only want to be with you

Following the story laid out in the previous lyrics, this last verse seems to be present day Paul being ever so self-aware that one of his greatest weaknesses is not being able to show/tell people that he loves them or that they are important to him. And he’s come to the understanding that this is what John needed to hear/know to believe that Paul never stopped loving him, knew a good thing when he saw it (warts and all), and was still committed to their partnership. So this song is just another one of those attempts to make John (somewhere across the universe) see that Paul “will always be there.”
