The rumour that Paul McCartney died in 1966 has been around for decades.
For those unaware, the legend goes that following a Beatles bust-up, Macca sped off in his car, and while distracted, hadn't noticed some changing traffic lights. He was then reported by some accounts to have been decapitated in a car accident and replaced by a lookalike by the band's management.
The myth picked up traction around 1969, when on October 12, a caller to Detroit radio station WKNR-FM told disc jockey Russ Gibb about the rumour and the "clues" people say suggest it is true. Gibb and other callers then discussed the rumour on air for the next hour, and the myth then exploded in popularity.
