Gness...the freat thing about the helicopter when I first saw it, was that nobody was expecting it. I saw the first performance and everybody just went berserk, because we never saw it coming. I was sat in the first row of the stalls and I could feel the wind from the blades where I was sitting.
Nowadays, social media would have given the game away within hours but this was the late 80's and no internet ,and therefore no flipping facebook !
Difficult to imagine life without the 'net !
