Just before the closing credits, the entire cast is assembled on the cobbles which they have just saved from being tar-maced over. Ken proposes a toast and everyone raises their glasses of champagne. Look in (I think) the bottom left hand corner at Sarah Lou. Not only does she not have a glass, but she makes it pretty obvious as she is standing right in front of the camera, raises her arm anyway, but looks round as if to say 'oh I am making such a fool of myself'. Admittedly it was live and time was short, but surely the props department should have made sure the people directly in front of the camera got a glass?
