You're right, Pan, you didn't use that term and I'm so sorry. I'm at a loss for where that came from. I guess I deduced it from your actual comment about Paul.
As for Paul, he made an enormous creative contribution to The Beatles and I am a big fan of his early solo and Wings work, too. I tend to not to give him too much grief for his latter day work because this sort of thing is very typical of musicians who manage to stay in the business for so long. Take Stevie Wonder, for instance, his cohort on Ebony and Ivory. It doesn't take away from my appreciation for his earlier work or the respect I have for him as a formative member of arguably the greatest rock band of all time.
George most certainly came into his own. All Things Must Pass is probably my favorite solo Beatle album. Again, some of his later work was a bit on the "pop" side, but it's also important not dismiss the entire body of his later work on the basis of the couple of singles from those albums. Even still, I like I've Got My Mind Set On You - maybe I'm just biased, though - I can find something to like in anything Beatle.
Then there is the Traveling Wilburys - of which he was key in its formation and direction.
Yes, Ringo didn't do as much after The Beatles and yes, we can be frank, he simply is not as talented a musician or songwriter as the other three, but I like the solo work that he did and I believe his presence and personality were key to the cosmic stew that could only be The Beatles - of which no single part was expendable.
I'm sorry again for misconstruing your words and I suppose as long as we are both humongoid Beatles fans we will always have something we can agree on.
