We have (almost) completed the crossword and the only four letter space left was 35d, where the checked letters IS?E led me to put in the word "ISLE" but I can't parse it. The other one I can't figure is 30a: the only word that fits with all the letters we have is "REPRODUCE" and the only unsolved clue is "Ace splitting atom with electrical charge" and I have no idea about thateither!
I have 35d as ISLE for Clue 'One before auction losing a key'
I (one) before SALE losing A
I have 30a as REPRODUCE for 'Copy expert getting into trim'?
I'm confused now!
"Ace splitting atom with electrical charge"
Answer is Brigadoon - the unchecked letters are IAON which is Ace splitting ION (electrical charge) - lyric written by Alan Day Lerner!
