Thanks Quisling - I didn't think that there was. I'm all done now in terms of the grid fill with the 5 thematic answers appropriately highlighted. I will circle the others but haven't got enough crayons to highlight them all, so I won't bother with that. I haven't a scooby what the two answers are that hint towards the work, but I'll revisit that bit later. My only minor gripe is that some of the corrections made to the misprints are, IMHO, slightly unfair, particularly those in 21d and 18d and 38d had several possibilities - but still a very enjoyable puzzle.
