Fifty years on and the rumour has not been disproved

The story’s persistence has been sustained by ongoing media interest. For one American radio special, a song was commissioned entitled “Brother Paul” that was credited to Billy Shears & the All Americans. In 1969, a TV court room procedural called ‘Paul McCartney: The Complete Story, Told for the First and Last Time’ provided ‘witnesses and evidence’ and encouraged people to make up their own minds. In 1979, a special called ‘Is Paul Dead? Turn me on dead man’ introduced more clues and rekindled interest in Paul’s death. Another documentary was called The Winged Beatle. As recently as 2009, a Wired Italia magazine article featured an biometric analysis by two scientists of the skull in photographs of McCartney taken before and after November 1966 and claimed these were two different people. At Beatles conventions, true believers still insist the “real” Paul is dead.^[1]

[P1] There has been sustained interest in the 'Paul is dead' theory. [P2] This demonstrates that there's something to the story.
