Paul gave a story about a moped accident--an "accident" that most of the press claims happened on December 26, 1965. But when you listen to how Paul phrased his reply to the NME interviewer, it tells another story. Paul says that he had "ONLY JUST" bashed his tooth at the time The Beatles filmed the promotionals MAY 19 and 20, 1966. I was curious about the Briticism "only just", so I
checked the Oxford English online dictionary and they give the following definition of "only just":
1.1 Very Recently
(example): 'I'd only just arrived back from Paris.'
Now take a look at a screen capture of Paul at the NME Poll Winners Concert from May 1, 1966:
NO broken tooth. And no scar on his lip.
So the timeframe for Paul's "accident" would really be sometime in early MAY, 1966. And because Paul insisted on showing the broken tooth in the promotional films, I'm guessing the cause was NOT an accident.
