Flash mob music video

Does anyone want to be in a music video on Saturday? If you're in Amsterdam bring your laptop to de Balie on Leidseplein at 11.30am. It's for a song 'Wifi?' about trying to get online. I'll sing at 12 noon and then everyone starts dancing at the end with their laptop, while people look surprised. If you haven't heard of a flash mob before, it's when people assemble in a public place at a specified time and perform a pointless act. There are lots of good examples on youtube. But it'll only work if there's lots of people.
