Wow Chris what a great post!! Fantastic to have some "inside" information on Bert, I didn't realise he'd worked with Pat Lundy, another fine talented artist. Like you say he does have amazing career credits which is one of the reasons we found it so strange that he remained such an enigma to us.
Please feel free to add anymore info it is MUCH appreciated, and the prospect of some photos of the great man in action so to speak is probably gonna keep me awake all night!
Thanks very much, Cheers Paul
