BTW In the Myles Palmer biography, Richard Kelly says that the demo was recorded in a London studio, but Dave Johnson says it was recorded in Bramley, Leeds. It seems most likely to have been Leeds, I think.
In that book other character that I can not recall says it was recorded in Leeds. Also the mknews official biography.
In the Oldfield Book David says it was in London, but maybe it's a mistake
btw great story, thanks to Mimmo ! and thanks to all for giving us the chance to listen to this piece of history
I am not surprised that the voice si so different, and I think it's Mark singing
