I don't really see how this idea can be counter-productive, even at this stage, as long as loud rock bands and DJs/MCs, with portable power supplies, are always firmly discouraged. …..Smiles.

But I think that we may as well face it, one such gathering will not do much good. We are in for a long haul.

I see it as just providing a spot in central London where local and visiting musicians and can gather and jam. It could be a regular gathering, say on every Sunday, the traffic noise will be (slightly) less then.. It could always be promoted as a tourist attraction and would form a handy and colour-full backdrop to any media coverage of the issue.

Pretty much as the long-running gathering outside South Africa House was, if hopefully not quite so long-running, but possibly could always be swelled on a particular day or week, from us country bumkins?

London's Speakers Corner has its speakers. Where will Musicians Corner be?

The legalities, necessary permissions and conditions I think are the first priorities. How about an approach to the Mayor of London? Or is that not a good idea? Any experts?

Is Parliament Square a good spot, or even possible? It is very visible, if very traffic noisy.
