Pavarotti's greatest performances

Joan Sutherland, interviewed on Today this morning about the death last night of her erstwhile protégé Luciano Pavarotti, was asked whether the great tenor's memory would survive.

But now, of course, in an age of near-perfect recording technology and the internet, the sound of these voices stay with us forever.
