I've been trying to parse these three all morning without success.
8a For once , it's the puzzler's answer. Ans clue -but where does the "for once" fit in?
20a Infuse dutch courage. Ans inspirit. You can get Dutch courage with drinking a spirit but how does infuse = inspirit.
23a Advance a pound at last. Ans lead -but how does a pound at last work? Thanks
