Christine did talk to him about it. The first song said : 'each detail exactly as she said' or something to that effect.
Glad you liked it too.. though the flashbacks were confusing as there is some discrepency with AGE. The script said Giry is in her 80s and Roaul is in his 60s, the she seems infinitly more spritely.
I am listening to the ost now. Its basically the whole film without pictures! I'm not a fan of dialogue in cRAB though,,,
