Tonight at 9 PM EDT, cable channels VH1 and VH1 Classic will simulcast a live show James Brown did in Boston in 1968, right after MLK was shot. At the time, this was shown on Boston's public tv channel, WGBH. Strangely enough, none of the Boston commercial TV stations wanted to carry it.
"BOSTON, Mass. - April 04, 2008 - On the night of April 5, 1968, white Bostonians were huddled in their houses, fearful that race riots were about to engulf the city the day after Martin Luther King Jr.'s assassination. As it turned out, black Bostonians were huddled in their houses too, because Channel 2 was about to air a James Brown concert from Boston Garden.
The story of that time is at the heart of a new documentary, which airs on VH1 Saturday night, the 40th anniversary of that concert. "The Night James Brown Saved Boston" isn't really a documentary about the 1960s or Boston per se, but it's as riveting a record of that time and place as you could hope to see. "
