Yes, I agree, roslyn - although the bad ones bother me most.
I think I might have an idea why they're special - but I'm still going through the letters, so not yet sure.
I thought the 'special' answers might comprise all of the letters in the unclued quotes + the two place names but I miscounted (55 for one, 56 for the other).
As for the eleven (apparently) random words in those clues - I've got no idea, but I can see all fifteen definitions now, so I'll leave it there.
