Irony: I got ripped the other day for saying what Paul has apparently said himself!
I think this is a good sign. Paul admits some of his stuff has been subpar. I think he wants to get back to the McCartney of his glory years. Maybe the albums since Flaming Pie are working back to that.
He just needs to keep the lyrics real--whatever that means. Not goofy, not sentimental, not syrupy, not blustery. But real. The real Paul McCartney, who, it seems, is at bottom a damned decent guy and talented musician who needs to take himself seriously but not too seriously.
I like the song he did about Lennon on Flaming Pie, because you could tell it was real. Now he needs to choose his subjects and get back to the core of what he was. I think part of the problem is evident in a quote from a Q magazine interview: "But most of my songs are not specific."
Get specific, Paul. That's what John was always able to do--to pull out of you. The Eleanor Rigby's, the Penny Lane's, etc. Specifics!
I think we all would like to see it happen. We all want Paul to have one more golden age, just like we want to see Brian Wilson have one, or Dylan, etc.
Personally, I'd like to hear an album where Paul went to town on the bass, like he did in the 65-69 years.
