"Paul Is Dead" is an urban legend and conspiracy theory that claims Paul McCartney, a member of the famous band The Beatles, died in 1966 and was replaced by a look-alike. The theory suggests that clues about his supposed death can be found in The Beatles' music and album covers, leading fans to believe that the band was communicating this secret through their art. The rumor gained significant traction in the late 1960s and early 1970s, fueled by various interpretations of song lyrics and visual symbols. Despite the widespread speculation, McCartney has publicly denied the claims, and the theory is widely regarded as a hoax.
