The live versions (I think?) of some of the songs are on Youtube. There are Elizabeth and Austen's duets "When I Fall in Love" (https://youtu.be/LvDc9MUJJzc) and "Had I Been in Love" (https://youtu.be/4_PyOgnQ62Q), as well as "The Portrait Song" (https://youtu.be/sSUo8z_xDc0), and the finale (https://youtu.be/9HslH5uz9vU). I'm fond of those ones mostly for the shots from the performance itself (although my favourite song in itself is "The Portrait Song," I've probably listened to the finale just as much for the adorable shots of Darcy and Elizabeth).

But also, some of the official recordings are on their Soundcloud, here: https://soundcloud.com/jas-pride-and-prejudice/sets/demo.
