Some of you may be unaware, but Deschanel is also a respected musician who has previously teamed up with singer/songwriter M. Ward to release a couple of albums (recorded under the moniker She & Him).
Ward is also onboard with her here, and a new version of the Winnie the Pooh theme will appear on the soundtrack, along with some original songs too, including one called So Long, which will be played over the end credits.
