Can you please help me identify this Mozart-sounding piece from a documentary?

Hey everyone,

I recorded and uploaded a segment from a documentary here: http://www.youtube.com/watch?v=g4WTeork658

Could anyone identify this song? It sounds like Mozart or Haydn I think. There's a piano, violin, and a flute, and it's in E flat major.

Thanks everyone!
