Bjorn & Benny (Abba) wrote this musical a long time ago and it is now being translated into english for tours through north america. This clip features a song called "Du måste finnas" (You must exist) and is sung by lead actress Helen Sjöholm. Broadcasted on Swedish TV2.

Here is a link to the english version although I find it to be less powerful, and please note that the english lyrics featured in this performance isnt necessarily the final draft: http://www.youtube.com/watch?v=H5GNnO0cCwg
