Anon1990 confirmed for brawl - will book train tickets in a sec.
I'll have my phone (loaded up with various lulz tunes) and my little megaphone so we can get a make-shift sound system going. It worked well in Plymouth last week on the street at half volume so this time it's going up a notch - just need some dedicated batteries for it (sharing batteries between that and your camera isn't a good idea).
This month I suggest that we go back to disconnection since families are traditonally together at Christmas. Signs like 'Will your family be together this christmas? Scientology families won't - ask us why' and various other better slogans are my line of thinking.
I will also look into getting some battery powered christmas lights to drape over myself. I'll link in from e-bay when I find something cool.
*sings*
Deck the orgs with caek and lulz,
la la la la la la...
*coughs*
Checklist:
Plod - Dealing with it (I've got Shifter's old letter)
Megaphone - needs batteries but it's there
AnonPhone - got it but needs more lulz tunes (suggestions welcome)
Flag - On it's new shorter, half melted flag pole!

Lights - on order
Rain gear - getting an umbrella
EDIT:
Portable 4M 30 LED battery powered fairy color lights on eBay, also Fairy Lights, Lights, Lighting, Home Garden (end time 21-Nov-08 06:43:09 GMT) - these looks pretty good for just over a fiver. I'm coming as a Christmas tree - just gotta find that green jacket. Hmm...
Hmm... I think evening raid might be a good idea? Raid from 11 til 1 then to the pub and then back onto the streets when it's starts to get dark ie 3-5 or something.
Also, Windy - meeting point is St Augustine's Parade at 11am. You forgot to mention that.
