The white trousers that David Hemmings is wearing in the film i have a pair of them, How this came about was after filming a lot of the children who lived in the street Princes Place had home made Gokarts. alot of the crew including David Hemmings used to have a go on these Gokarts, David Hemming went too fast fell off, on a lot of dirt and oil so my dad gave him a pair of his trousers to wear.
