On October 30, 1970, Jim Morrison was sentenced to six months in jail and fined $500 for exposing himself onstage during The Doors concert at the Dinner Key Auditorium in Miami. The show took place on March 1, 1969, and is probably one of the most infamous concerts in rock history.
The trial started on August 20, 1970, and Morrison was eventually convicted of two misdemeanor counts of open profanity and indecent exposure, but he never served any jail time. He appealed the conviction, and according to the Miami Herald, was released on $50,000 bond. Then in 1971, Morrison went to Paris we he remained until his death later that year.
In 2010, the Florida State Clemency Board granted a pardon to Morrison for his crimes.
Below is a must see video from the archives featuring authorities publicly issuing an arrest warrant after the concert in Miami, fans talking about the show, and Morrison himself answering questions about nudity from a reporter.
