3. Katherine Jenkins
Now, if you want a powerful voice, who better than welsh diva and all-around lovely lass Katherine Jenkins? After all, look what happened the last time a Bond tune was sung by a Welsh woman with a hell of a voice! Although her voice is very different to Shirleys, an operatic ballad would be a very welcome new type of Bond song. I imagine the accompanying credits would have trouble keep up. Many Bond scores take motifs from the instrumental of the opening song, so the soundtrack would be very interesting.
