"Paul is dead" is an urban legend alleging that Paul McCartney of The Beatles died in 1966 and was replaced by a look-alike and sound-alike.
The legend hinges on supposed hints among the Beatles' many recordings and presumed to be deliberately placed by The Beatles or others. Hundreds have been cited at various times; they include statements heard when a song is played backwards, symbolic interpretations of obscure lyrics, and ambiguous imagery on album covers. Some of these have become well known, such as the fact that on the cover of Abbey Road, McCartney is the only barefooted Beatle and is out of step with the others.
It is often unclear how many proponents of this story spread it as a joke, as opposed to a real conspiracy theory. The rumour has been the subject of much sociological examination, since its development, growth, and rebuttal took place very publicly.
A claim that a hoax was perpetrated by The Beatles themselves, either as a joke or to stimulate record sales, was denied by all three original band members.
