In early 1969 Knight secured a producer's contract with Capitol Records which also allowed him to release his own songs as a solo artist. He wrote and recorded a single, "Saint Paul", which may have contributed to the "Paul is dead" hoax that erupted late in the year. The cryptic lyrics of the song are generally thought to allude to Knight's failed relationship with McCartney and his apparent belief that the Beatles would soon break up. The lyrics do not refer to death but were interpreted by some fans as containing clues. The ending repeats the phrase "hey Paul" in an arrangement that sounds similar to the Beatles' song "Hey Jude". There are two versions, both in stereo. The full five-minute version contains a high-pitched voice singing lines from Beatles songs, including "Hello, Goodbye", "Lucy in the Sky with Diamonds" and "She Loves You", while the four- minute edit does not contain additional song excerpts.
