In reply to Richard Alderton:
Traditionally it was jam yesterday and jam tomorrow, never jam today, but the idea is the same. There was a scene in a Peter Cook, Dudle Moore film about hell -
'We are in hell. It is 5 minutes to opening time'
'That doesn't sound too bad, you can have a drink in 5 minutes - why is that hellish?"
'No, you don't understand - its always 5 minutes to opening time'
