Noise will play a large part in the protests on Saturday. Here is an important announcement about the 2pm happenings, and more notes and call-outs for anyone interested in sound, making sound, and making mischief.

Soon after 2pm, in preparation for the events at exactly 2.11, samba bands and sound systems are urged to quieten down. People will begin to shush the crowd, and an eerie silence will come over London.

Then at 2.11, the noise (and the occupations) will begin.

If you have a sound system, please download the mp3 of air raid sirens, and let the Battle for Britain commence at exactly 2.11. If you play with a Samba band or other music outfit, then please pass the message on and arrange quiet soon after 2 and an almighty din at 2.11

If you have a voice, tell all your friends - quiet after 2, shush the crowd, scream shout and make animal noises at 2.11.

You can also make a simple but effective natural megaphone with some stiff cardboard. Just form a cone shape and stick a basic handle on it. The bigger the better.

You can also listen to the X26radio web stream broadcasts throughout the day, with regular protest news on the hour every hour, and of course, the same quiet and big bang after 2. ( http://london.indymedia.org/articles/7941)

Do you have a good protest song? - something new, but easy to teach and sing? if you have an idea then just add a comment at the 'arts against cuts sound page ( http://artsagainstcuts.wordpress.com/songschantsgamestheatre/), and share it with all

London choirs and vocal groups as well as anyone interested in helping with fliers, megaphones or sound systems, are invited to a meeting on Thursday March 24th at 2pm, Room 305 at 272 High Holborn on the third floor.

If you are able to help with distribution for half an hour to pass round the words of protest songs to the crowd at embankment on Saturday morning (from 11am onwards), then please contact to offer your help.
