Anyone know the singer of the bonus cue "Again" in La-La Land's Riddle/Batman CD? And where is the song featured in the film (if at all)? Also, who is singing the Plaisir D'Amour song in the main program (track 11)? Thanks.
To answer part of your question, "Again" does not appear in the film proper. It may have originally been intended for the spot "Plaisir d'Amour" eventually took, or for use as source-underscore for some point in the romantic subplot. A charming song, and something of a running gag in the Fox music department (I heard it crop up in some movie I watched recently, though naturally I don't recall which one).
