This is so so sad, I'm the only one responding to my own thread :-(

Anyway, just in case there is some interest in this and Icehouse
theories, this is the BBC link

http://www.bbc.co.uk/radio4/science/...ialworld.shtml

and can be listened to over the web if you missed it.


Some of us were at work when you originally posted so may not have been able
to reply.
But I'll try and listen to the web link.
