I finished this OK, but couldn't fully
parse three of the clues, which are:-
7 Down - "Last order in pub? NI party
hides green strip"
Answer is "drink up" but I couldn't
see where the green strip came into it!
20 Down - "I aim somehow to grab drunk
policemen with arms"
Answer is "militia" but where do the
drunk policemen fit in?
5 Down - "Praise god of marriage,
not Earth"
Answer for that would appear to be
"hymn" but I haven't been able to
associate "Earth" with anything!
Anybody care to sort me out?!
