Just come across a paper published in the Irish Medical Journal in 2007, ‘A Cure for the Soul? The Benefit of Live Music in the General Hospital.’ No particularly revolutionary conclusions, but nice to see a proper piece of evaluation rather than advocacy. Also, it is refreshing to actually be able to access the content rather than clicking on the paper only to find that it takes you to a journal subscription page (I understand journals have to charge something but wish more of them would price with freelancers in mind as well as institutions).
