You are right; it is 14d. However, I am still having problems understanding the wordplay in 14a, 15a, 16a, 37a, 24d. Nor can I obtain the reassembled clues for 23a or 25a. And if the reference to a musical work is a rock album I am going to be completely out of my comfort zone.
However, there is plenty of time to think about this.
