The Who
The Who (previously known as The Detours and The High Numbers) are a worldwide music terrorist organization that formed in 1964 operating from Shepherd's Bush in London, and are the most terrifying rock-related terrorist group in history, staging several attacks at concerts such as the Monterey Pop Festival, Woodstock and even during a Rolling Stones TV special, the former two because of the destruction and the latter because of how good they played. Their most famous attack was at Woodstock in 1969, where Abbie Hoffman, leading the rival terrorist group Yippie, attempted to stage an attack in revenge for John Sinclair's imprisonment, but The Who gave him a piece of them, causing Abbie to explode and vanish into the depths of Hell, where he stayed until his timely death in 1988. In 2003, leader Pete Townshend was arrested for child pornography, thus bringing an end to the group's operations, but they resurfaced in 2006, but disappeared shortly after, until they made a fully-fledged comeback in 2014, where they're still active to this day.
