If it's kosher then we should all get really excited about it. There's mention of :-
Plumstead Sinfonia - never knew there was one
Plumstead Manor Musicians - these are real human beings and they definitely exist
The Bill Mudge Quintet - Google (and other well known search engines), confirm that BMQ are real, but I couldn't find Plumstead Live! on their tour schedule.
So, is this a red herring? Maybe Greenwich Council smoke and mirrors to 'bury bad news'?
Is such an event too good to be true? Gadzooks!!!! I hope not.
