Recommend background music for a documentary?

[wordoflife]

I'm creating a documentary for a school project and need advice on some background music I can use while we are speaking in the video. It's going to be a historical documentary ... any ideas?

I'm not going to be publishing the video or posting it anywhere, I'll just be playing it in class so I'm not concerned with royalties and stuff like that.

Thanks for the help.
