I sent a letter asking some questions and SAE to Chris on: 12th January 2009, and today I recieved a signed photo back with my questions answered on the back.
address I used was:
Chris Gascoyne,
c/o New Theatre,
Park Place,
Cardiff
CL10 3LN
Just my opinion: But I don't think that celebrities would answer honestly if they have a Facebook/Bebo. If they do, it is more than 90% a personal one. Seems like the only way to post feedback about them is through MySpace, if they have one that is.
Either that, or writing to them
