Jim Morrison was so rebellious that he's been dead for 42 years and he still won this poll in a landslide. In September 1967, right after "Light My Fire" hit the top of the charts, the group went on The Ed Sullivan Show to perform "Light My Fire." The producers told them to not sing the line "Girl we couldn't get much higher." Accounts vary as to whether or not they actually agreed to this, but on the live broadcast, Morrison definitely sang that line. They were banned from the show, which basically played to every living room in the country.
It was a costly move, but Morrison was just getting started. He was the original Axl Rose, showing up late for gigs and taunting the crowd when he did show up. People have been debating for decades what actually happened in Miami in 1969, but even if he didn't reveal his penis, he certainly taunted the police until they arrested him. Moves like that really damaged the band, but Morrison seemed not to care. He died in Paris in 1971, but some fans refuse to believe that and they're holding out hope he's going to re-emerge some day.
