It's the same old story though isn't it Goff, we're reaching so far back into the mists of time that little is for sure. Almost a blank canvas for people to paint their own theories upon; finish one canvas in that series then start on another, and before long you've got a whole gallery that's full and makes perfect sense to the painter - but in reality hangs on the slimmest thread of 'perhaps'.

Each bit of evidence (even those bits that are subsequently shown to have been misinterpreted) are of value though, and I agree with you totally when you say 'it's always a good thing to get people interested in these things, and it's always nice to see such coverage on national telly'.
