What am I going to do?

Having visited Trafalgar Square a few times to see how the Plinthers are getting on (and, anorak that I am, suss out the mechanics of the whole event) I've abandoned my original idea of just standing on the plinth looking like a statue. This is mainly due to the abuse I heard one plinther receive for "not doing anything". Whilst I don't think it is necessary to "perform" in terms of the artwork itself, as my wife is intent on bringing a coachload of friends and family to witness my turn up top, I feel duty bound to stop them from being bored! Currently I'm thinking of breaking the hour into four distinct segments. The trouble is I need a couple of questions answered with regard to whether I can take a megaphone up there and what the situation is with regard to playing a CD or two over a small PA system. If you want to see how I get on ....... watch this space!!
