I was more impressed by the apparently mostly spontaneous dancing (seemed to by many passer-bys, but could have had a few 'initiators') than anything else.

It was clearly a planned directed (and not a spontaneous - or 'flash' as it is called today) event, it even had an 'orchestra leader', who synchronised the start and finish, as well as having somebody who had organised a communal playlist, content and order. Probably a 'festival' event.

Of course I speak as someone who was trained in the 'Classical Symphonic Music' style :-) Expecting such a thing to happen without some previous rehearsal/organisation is laughable to those who have experienced the 'herding cats' syndrome often experienced in 'Folk Music' circles. Of course, many who do PLAY Folk Music ARE Classically Trained Musos.... :-)

As to any imagined 'problems' due to the members of the 'orchestra' being scattered around, you would only laugh if you were 'Classically Trained' - that is nothing new in this 'style'.... :-) The 'leader' knew what he was doing, and the rest knew how to 'take direction'... the result is much more exciting and entertaining than a 'normal' 'just belt her out as loud and fast as you can' 'session'.... :-)

Seemed like a 'Portsmouth Synfonia' event, but with a slightly better class of Muso, I think .... :-)

Should be MUCH more of it.
