Perhaps we need to be using music in our campaigns more, just like they used to do in war-time to inspire people to take up helping out with the war-effort (and getting young men to sign up!)
I talk a little about the importance of art and music in our campaigns in my book (though I am speaking of campaigns of an environmental nature). Any medium which has a way of tapping in to the consciousness of our audience, drumming up empathy, and generally improving your overall P.R is worthy of consideration. No doubt Wayne Swan (and his daughter) has caught on to this.
