Yes, it would be worth checking out when you get to that point Deb, and as it's only the one song it might be worth using anyway if you feel it would work.
Mine was a Blur song, but I had others in mind by The Lightning Seeds, Pulp, R.E.M., The Sawdoctors and Manic Street Preachers too, so I think it would prove rather expensive if I went down that road. Clarifying the situation re: copyright has got me back on track with my editing though, so I'm glad I asked the question!
