This was for the John Sinclair Freedom Rally. In 1969, Sinclair was arrested for possessing marijuana after he gave two joints to two undercover cops. At the time, if you possessed marijuana, they would basically throw the book at you. John got TEN YEARS [[hence why the concert was nicknamed "Ten For Two").

Stevie was the only Motown artist, the only R&B artist, and, as far as I know, the only African American artist, to take part in this rally. Must be something about Stevie [[and Lennon since he organized the rally with Yoko Ono) because after that rally, the state of Michigan declared that Sinclair's conviction was unconstitutional and he was freed.

I don't know if he ever got pardoned for it but this was why Stevie was there.
