Joan Sutherland as Lucrezia Borgia in 1989

Joan Sutherland sings the finale of Donizetti's Lucrezia Borgia in a performance that took place in Paris, June 17th 1989. She was almost 63 years old. I'm not sure whether this is due to the recording or not, but apparently she did sing only the "da capo", still with a ringing and full top note in the end!
