A Bandstand for the 21st Century?

As you may know Plumstead Common used to have a Bandstand, it was located at the western end of the Common, near Blendon Terrace. The Adventure Playground now occupies the site. It was demolished in the 1970's apparently following arson attacks and vandalism. There is an urban myth that it was in fact dismantled and is lying in some forgotten council warehouse.

You may ask why am I blogging about this long gone and mostly forgotten relic of the Common's past, the reason is that I have an Idea and I want to know if people think it is a good one or have I in fact just gone quite mad?

My Idea, a new bandstand 'for the 21st century, I am not talking about some modern unused pastiche of a 19th century icon, but an open air performance space for the many communities of Plumstead. The Victorians knew a thing or to about making urban living civilised and bringing culture to the masses, hence among many other things, bandstands so why can't we update the idea for now and do something really exciting for the area?

I hope to get the PCEG involved and this is an extract of what I wrote to the chair, Nick Day:

'...one of the historical losses from the Common was the demolition of the Bandstand in the 1970's. But I have a vision for a 'bandstand for the 21st century'. It wouldn't be somewhere just for brass bands on a Sunday afternoon, (not that there is anything wrong with that, I think that would be fabulous in itself), but I was thinking more of a multi-use open-air community performance platform that could host music, dance, theatre, and even be a venue for a big screen during the 2012 Olympics.
I had a look at the 2012 website http://main.london2012.com/en/ourvision/olympism+and+culture/ and in particular the pdf file on the cultural update on 2012 http://main.london2012.com/NR/rdonlyres/00006717-77A7-4285-90AD-A1896E051202/0/Cultureupdate210607.pdf
..... and I think if we move fast and can get local people enthused there is real potential for the funding of such a project, which I think would bring about a real legacy benefit for the area. It is also the kind of project which might just inspire the younger generation to participate....
..This may just be a pipe dream on my part, but I think it has the potential to be something really exciting. When I have travelled on the continent I have always been struck how even relatively small towns have cultural festivals, performances etc. often in a town square or similar central location, and I don't see why Plumstead can't do something similar.'

Now this is one thing where I would really appreciate hearing what people think, is it a good idea or have I just gone nuts?
