On April 5, 1968, a day after the assassination of Martin Luther King, Jr. in Memphis, Tennessee, Brown provided a free citywide televised concert at the Boston Garden to maintain public order and calm concerned Boston residents (over the objections of the police chief, who wanted to call off the concert, which he thought would incite violence). The show was later released on DVD as Live at the Boston Garden: April 5, 1968. According to the documentary The Night James Brown Saved Boston, then-mayor Kevin White had strongly restrained the Boston police from cracking down on minor violence and protests after the assassination, while religious and community leaders worked to keep tempers from flaring. White arranged to have Brown's performance broadcast multiple times on Boston's public television station, WGBH, thus keeping potential rioters off the streets, watching the concert for free. Angered by not being told of this, Brown demanded $60,000 for "gate" fees (money he thought would be lost from ticket sales on account of the concert being broadcast for free) and then threatened to go public about the secret arrangement when the city balked at paying up afterwards, news of which would have been a political death blow to White and spark riots of its own. White eventually lobbied the behind-the-scenes power-brokering group known as "The Vault" to come up with money for Brown's gate fee and other social programs, contributing $100,000. Brown received $15,000 from them via the city. White also persuaded management at the Garden to give up their share of receipts to make up the differences. Following this successful performance, Brown was counseled by President Johnson to urge cities ravaged from riots following King's assassination to not resort to violence, telling them to "cool it, there's another way".
In January 1998, he spent a week in rehab to deal with an addiction to unspecified prescription drugs. A week after his release, he was arrested for an unlawful use of a handgun and possession of cannabis. Prior to his death in December 2006, when Brown entered Emory University Hospital, traces of cocaine were found in the singer's urine. His widow suggested Brown would "do crack" with a female acquaintance. 2b1af7f3a8
