Myths and Legends:

Myth #1 Robert Johnson sold his soul to the devil:
According to the myth, Robert Johnson always strived to be a famous Blues musician. He was born in Hazlehurst, Mississippi, where he lived on a rural plantation for all of his life. Striving to be a great guitar player, he took his guitar to the crossroads at midnight. At midnight he was met by a large black man who is said to be the Devil. This large black man took Robert's guitar and tuned it. Once the guitar was tuned, the Devil played a few songs and gave the guitar back to Robert Johnson. This gave Robert Johnson the ability to master the guitar. This is called the "Deal with the Devil". Over time the legend has been developed and changed, but some people still believe it. No one really knows, still, if Robert Johnson actually sold his soul to the devil to play the guitar or not.

Myth #2 Ozzy Osbourne's taste for doves and bats:
It was said that Ozzy Osbourne bit the heads off doves and bats. This myth is actually true. In 1981, Ozzy went to a record deal meeting, in Los Angeles, where he bit the head off of a dove. His plan was to release doves into the air during one of his performances, but he was too drunk and he it the head off of the dove. This act has been alluded to several times throughout his career, which helped to make his career and was one of the reasons he became famous. Also, at one of his shows in Iowa, he was thrown a "dead" bat, that he believed was rubber. With his belief that the bat was rubber, he continued to bite the head off. The bat was not only alive, but bit Ozzy onstage, where after the show he had to get a rabies shot.

Myth #3 The mythology surrounding the Abby Road cover:
The myth is that in 1969, a DJ received a call from a man named "Tom" who claimed that some Beatles records contained hidden clues that suggested that Paul McCartney was actually dead. The theory is that Paul was decapitated in a car wreck after he had left the Abbey Road studio. Paul had left over an argument and took his Aston sports car, and he perished in an accident that killed him and he was replaced with a look-alike. The myth behind the Abbey Road album cover is that the four Beatles are walking in a single file line across the crosswalk at Abbey Road. This is thought to symbolize a funeral procession. Also, John Lennon is dressed in white, which represents the Church and in some Eastern cultures, white is the color of mourning. Ringo is dressed in black, representing the undertaker and Paul is out of step with the other Beatles, and he is barefoot and his eyes are closed. In a number of societies, corpses are buried without their shoes. Also, in the album cover, Paul is holding a cigarette with his right hand, when in reality the "real" Paul was left-handed. Last, George Harrison is dressed in work clothes, and is represented as the gravedigger,too many. Another hidden "message" on the cover is that on the Volkswagen Beetle, the license plate showed "LMW 28IF" which indicated that if Paul lived he would have been 28.

Myth #6 The mythology presented in Sgt. Pepper cover:
The Sgt. Pepper cover the crowd surrounding the four Beatles, resembles the mourners at a funeral, and the flowers in front of them do not only spell out the name of the band, but a set of the yellow hyacinths form the shape of a left-handed bass guitar, which was Paul's instrument. Paul also had his right hand raised above his head, which in some Eastern societies is the symbol of death. Another sign is that all of the band members were holding bright, golden band instruments, while Paul was holding a black clarinet. This is a supposed symbol of death to some people. A doll also wore a striped sweatshirt that said "Welcoming The Rolling Stones", where on her leg is a small model car that resembles an Aston Martin that is heading toward "Stones". This is believed to be a clue to the accident. Also, if you open the album jacket, the Beatles are in Sgt. Pepper's uniforms and on Paul's arm patch it says "OPD" which is an abbreviation for "Officially Pronounced Dead".
