I wonder whether one should interpret the song knowingly, as some of the divas seem to do, or only interpret the surface meaning (which is probably the reason why millions of people have shed tears over the song, but then again, has or has not the hidden driving force anything to do with it?) and emphasise Cio-Cio-San's innocence. She longs for Pinkerton's return because she believes in him and in their marriage, for heaven's sake, and she is only eighteen, the same age as France Gall when she innocently sang 'Les Sucettes' written for her by Serge Gainsbourg. The damage to Gall's psyche was enormous when she found out later what she had been singing.
The third option, of course, is to refuse altogether to sing this product of patriarchal fantasy which oppresses not only a whole gender but also a whole race. (Er, do I sound a little angry? :-) ) But 'Un bel dì' is undeniably a masterpiece, despite its patriarchal limitations. Puccini and Gainsbourg. Hmmm. I do admire your talent, though, both of you.
