Hi Prospero and All,
I had lots of fun with this puzzle--thanks Picaroon! I think I've solved it, and I've submitted it, but there are two things I don't understand--one of which I got from the crossers in order to make what I think is the correct answer, and the other of which I got from the requirements of the theme.
If these questions--or answering them--will reveal too much, moderate me out, or don't answer them!
At 12 across, the 6th and 7th letters seem to have to relate to the final two words of the clue. I don't understand the connection, or recall having seen these two letters used in this way before.
At 22 down, the first letter is required by the theme, and seems to have to relate to the first word of the clue.
Again, I don't understand the connection, or recall having seen this use before.
