MI - yes, there will be a bloody (literally) mess, and there are pre-spattered panels currently leaning up against the piano 
. There is also a fake wall set with explosive charges with a sign on it warning us not to use walkie talkies or smoke, by order of the SFX Director. Obviously someone has changed SFX to SEX. I also have a security guard called George sitting in the driveway.
BTM - you do have to be very tolerant to have a film crew at your house as they completely take over, but it is indeed worth a bomb (which we need due to house's aforementioned habit of falling apart). Thankfully we have very little that is precious and fragile, and the bits we have I just move myself. So far we have found people to be very nice and very respectful - film and tv people, or certainly the technicians/art people, are a fun bunch. Oh and SW London crepeys, I have today met a Streatham-based female plumber who seems like a very good person and knows her stuff, so if you need a plumber, I'll give you her number. She does everything, (bathroom fitting etc) apart from boilers.
Oh and singing crepeys - ds2 passed his Grade 3 singing with a good pass only a smidge off a Merit, so I am v pleased. I had been fearing he would not pass as the bloody school decided that the last day of term was a good day to set up an exam centre, and then they were so disorganised about it (never done it before) that the kids were given no time to warm up before going into the examiner. Grrr. Ds2 is moving school this Sept, so it was his last day there ever and he came home in a right old state, full of tears and sweets, so I am not sure how he managed to sing through that.
