An online rumour of an unofficial Maria Callas recording of Verdi’s Don Carlo sent hundreds scurrying to Youtube this morning.
Forty years after her death, the Greek diva is still packing them in like no other singer in opera history.
She is the highest-selling soprano on record, the subject of several plays and the face that still launches products.
It can’t be the voice. Millions of words have been wasted analysing Callas’s vocal flaws.
Nor is her appearance so Hellenic that Troy would fall at the sight of her.
So what is it about Callas that keeps us coming back for more?
If there was a recipe, every opera singer would want it in a bottle.
