Sorry: just realized I forgot to post my own clue(not surprising considering its length)! Here it is for what it's worth, tho' really too late:
To frighten you as loudly as poss,I owe you & me, France & Spain, all those confused letters (10)
Expl.:
To frighten you: Fee Fi Fo Fum
as loudly as poss. & a bit louder: FFF
I owe you and me: IOU + ME
France & Spain: F & E
all those confused letters: anagram indicator
So either you ignore clue & vote,or accept both with apologies! I must be getting very old...Sorry again!
