I can understand people not giving away about the actual video, but you could still post a full blown report without any of that. eg we all assembled at location X at whatever time. We were told we would all be going to Croydon. How did you get to Croydon, what was the journey like, where was Mika did he travel with you or meet you at Croydon? What happened pre filming? Did you get your hair and make up done? How many extras there were? What time did you break for lunch? Was lunch provided? When did you get chance to grab piccies with Mika, was that before between or after fliming? That's just a few of the hundreds of questions I have ... sure I'm not alone, answers to none of these would reveal anything about what the video will look like. Come on guys, we want to know things about the day that to you are probably trivial, but to those of us who weren't there are really interesting.
Edited to say posted simultaneously with Jack ... great minds!
