James Brown, keepin' the peace on WGBH

A new DVD set about James Brown features a documentary about the legendary soul singer’s performance in Boston the night after the Rev. Martin Luther King Jr. was assassinated — a performance that aired on Boston’s WGBH-TV. Commentators in The Night James Brown Saved Boston credit the station’s broadcast of the show (which pre-empted a Chekhov production) with preventing riots from erupting. The Wall Street Journal reviews the doc.
