Hi again
Still a few to do and like many of you troubled by the four and six letter words in the corners. I also have two of the eight letter words to get.
Thank you Brendan for your hints. In fact I had managed to solve the anagram for 8ac on my own. I was thrown by Maskarade using Virgin in both the anagram and the definition. I know the colour well.
Thanks for other hints as well that have pointed me in the right direction - organ stops and Brazilian dances.
I'm not sure I'll find time tomorrow to battle on. It does get a bit obsessive. You may hear from me again. Well done to those who have completed the puzzle.
