I'm glad I got the shapes late last night, that's a very big hint!
Very nice puzzle, or two puzzles really. Not 100% sure which is the correct one, I guess the one with the 'providers' name ? as that word is in the title.
I do have one 'hole', right in the middle of the shape!
I have S?NS and S?NA for 24a - Music's without alto, dead from then on.
Nothing seems to work, maybe I have a letter wrong.
Anyway onto Spectator now. Azed looks dull, I like the Azed specials.
