Fantastic ! What a sharp mind and tongue He had! He's like one of those mathematicians explaining the curvature of space-time in 2 minutes as if it was easy and saying "it's so obvious , if you don't get it, not my problem!". I love Frank and Kate Bush is right , He was a very smart man.
Anyone remember how Frank dealt with the improv dancing around some band members did on stage which obviously irritated him. How he would have the stage lights off and one spotlight on him the entire show. I think he did this for many shows over a couple of years in the eighties.
