Hi, Rusty!
Ah, "West", with "i's" in it...giving "wisest" = most sound (def)
I would never have got that!
I had done 15a as an anagram of "listener" so got "Leinster"?
When I googled that, it is home to a Rugby Club....fifteen team members?
Got "arvo " for PM (afternoon!)
But cannot do 23d?
So far, I have only got ?R??
I have seven more clues to go........
