Gorgo Bars I remember these in the vending machine of the swimming pool our school used to take us to for swimming lessons in Leicester in mid-80s. Been searching for ages for the wrong thing. I thought they were called Gorgon Bars. I remember they were like wham bars but green - however I remember the sour bits as being silver rather than black. I also thought it had a picture of medusa on the packet but must be a false memory.
