Quixote, thanks for your email relating to post 103 but you didn't mention post 61, today is the first time that my attention has been drawn to 61 which is strange as it was posted 3 days ago.
Malone, thanks for your post and email, your post sums everything up very neatly, there's not a lot for me to add other than to remind everyone about the content of Post 1 - PLEASE DON'T GIVE TOO MUCH AWAY IN HINTS OR IN NUDGES TOWARDS THE THEME.
I considered all points of view whilst having a shower, I had to stop thinking whilst I freed the water drain, and have decided to take no action in this particular case.
It is now Thursday so The Listener diehards will have finished the crossword long ago, the next Listener is out tomorrow, and I think too much time has elapsed since post 61 to take action there. As Malone says, the slightly more generous hints might have helped the less seasoned solvers.
