I suppose that this bluesy song is a kind of tribute but maybe could be a bash too, as we can see the lyrics:
You gave me something(like a songwriting partner)
You gave the love in the my palm of my hand(his friendship relation)
I can't tell you how I feel
My heart is like a wheel(But he has a confused and mixed feelings about it after the Beatles breakup)
Let me roll it
Let me roll it to you(Let the things roll, let it be)
I wanna tell ya
And now's the time(I think it was about the Apple Corps. process on the Court, the Allen Klein's question, when he did sue the other three beatle-fellows)
I wanna tell ya that you're going to be mine ( He was sure that he's gonna win the process)
Well, I think so but maybe is a crazy supposition.
What do you think'bout?
