well apparently Paul had a car accident in late 1965 which caused him to have a scar & chiped tooth which you can see very clearly in the Paperback Writer vido!
"Wenesday November 9th 1966 Paul McCartney DID have an accident, but this was a motorcycle accident on the way to his aunt Bett's house, and it did not happen at 5 o'clock. A local doctor was called, and the accident resulted in only a chipped tooth, and a scar to his lip. This is why in the "Rain" and "Paperback Writer" videos, Paul appears without a tooth"
His brother took this the night it happened:
So tell me, how come Paul has a clipped tooth when the video was shot on May 19, 1966?
