The Doors named themselves after Aldous Huxley's narrative about mescaline, The Doors Of Perception, which got its title from a quote by William Blake: "If the doors of perception were cleansed everything would appear to man as it is, infinite." Huxley took LSD on his deathbed and tripped to his death on November 22, 1963, the same day John F. Kennedy was shot.
On December 9, 1967, Jim Morrison was arrested at a concert in New Haven for breach of peace, resisting arrest, and indecent exposure. Police were called after he was seen backstage having sex with a young girl, and Morrison was angry that they were questioning him. The police arrested him when he exposed himself at the show, the first time a rock star was arrested in the middle of a performance. You can see him arguing with the police at the end of this video.
Without any further ado, Ladies and Gentlemen, from Los Angeles, California (insert intro guitar riff)
