Yep, he (Guido 'Guy' Fawkes) came pretty close to blowing up the Houses of Parliament on behalf of a Catholic plot ('Gunpowder Plot') in the 17th Century, discovered last minute stacking the last few barrels of gunpowder in the basement just as Parliament was about the meet. If it had happened it would have blown the whole place to smithereens. Since then his 'effegy' (with the usual moustache) is burned on numerous neighbourhood fires (getting rarer these days) and fireworks are expended (getting more common thanks to cheap imports). All part of the Protestant/Catholic religious troubles of those time that is still remembered. US-style Halloween of a few days earlier is threatening to push it to sidelines these days though, a sad trend.
Glad you enjoyed the Joe Henderson set. My pleasure to having chanced across Dusty's hype (for once, not unwarrented).
