the music

Does anyone know the names of the songs that open and close this film? The opening track is a piano song, I think it might be by Schumann, but I couldn't tell from reading the credits. It plays while the children are swinging in the park. The other song is playing at the end of the third story when Paula walks away from the donut shop after her car gets stolen. It's sort of an instrumental, jangly guitar song. I would love to have these songs on CD, but there doesn't appear to be a soundtrack recording available. Anybody know where I can obtain copies of these songs?
