Although this wasn't the hardest of crosswords, I've still been left with a couple of queries. The preamble says there is one unclued light of two words, but I have two. I always have another theme answer which appears once in the singular and once in the plural. That seems less than satisfactory.
I know this post won't make sense to anyone without the puzzle - sorry!
Thanks for the added info, djawhufc . The different meanings casts another light on it, but I think it looked worse as the answers are so close to each other!
I think the 'one two word answer' in the preamble is simply an error.
