This is a flashback to Paul appearing at Ringo's wedding in April 1981 to Barbara Bach, the actress whom Ringo had met the previous year whilst filming "Caveman."
Now, you could look at this photo in any of several different ways. First, just about anyone on earth would be thrilled to have Paul McCartney at their wedding. Certainly Ringo would have been happy to have him there, good old pals that they were (and still working together a great deal in those days). Just having Paul there makes it an event.
Take 2: But then, it was Ringo's wedding day. And you would think that an ex-Beatle on his wedding day naturally would be the sole center of attention. However, as the photo shows - not necessarily.
|Earlier that day....|
Taken another step back. Take 3: Paul could have just shown up, perhaps spent a quick five at the reception for appearances sake, and then split. Like, why not? Believe me, many people would do that, no matter how long they had known their friend who was getting married. But instead, Paul is a sport and makes an event out of it.
So, yes, plenty of different way to look at this depending upon how friendly or hostile you inherently are to all concerned. And there are people on all sides of that particular ledger.
Just to point a couple of things out: this is one of those rare shots where we see Linda smoking, cigaret in hand. It's terrific that whoever took this shot got all three in frame. Barbara, though, is noticeably absent. All those kids milling about now are grown up and wondering to themselves, "Was I really there when Paul McCartney was playing the piano at Ringo's wedding when I was five years old?"
Oh, and Ringo and Barbara are still going strong over 30 years later. So, maybe Paul was a good luck charm.
