The neighbours are planning a street party for the Royal Wedding and, assuming it's dry, we want to rig up a big screen so everyone can watch the wedding together as well as the football later no doubt. I know a lot of people have those roll-down cinema screens and other types of big screens these days, so assuming we could find a neighbour that has something suitable and is willing to use it, would it be reasonable to think it could be rigged up in the street, and, if so, what would it need to be plugged into? Or maybe we could hire something relatively cheaply? We just need enough of a technical steer so we can post the idea to our street Whatsapp group without sounding too naive
