ON Tuesday, the Mahogany Ridge regulars celebrate the 25th anniversary of the Purple Rain protest that took place on a rather damp Saturday afternoon on Cape Town's Greenmarket Square.
There were plenty of confrontations with authority in those emergency days, but this one was quite unique in how spectacularly it backfired for the security forces.
Though we didn't realise it at the time, apartheid was in the throes of a grand mal seizure and the thousands of Mass Democratic Movement supporters who'd poured into the city on September 2, 1989, to march on Parliament to protest the next week's elections were nevertheless expecting the worst from the security forces.
The police, it must be said, were looking forward to the clash. They had - clever clogs that they were - a powerful new water cannon which was loaded with purple dye to stain protestors for later identification and arrest, and couldn't wait to try it out on those who ignored their orders to disperse.
The fun and games started soon after the spraying began. A lone protestor leapt onto the vehicle on which the cannon was mounted and attempted to redirect its blasts away from the fleeing crowds and back towards the police.
But it was like wrestling an angry firehose or an anaconda, and the stuff went everywhere else instead with the result that most of the surrounding buildings, including the National Party's offices in Burg Street, were given a vibrant purple rinse.
