On 11th August 1999 a total solar eclipse occurred which was visible in parts of Europe and Asia.
One of the countries was Romania. On that very same day Pavarotti held a concert in the Romanian capital Bucharest celebrating this solar eclipse, a concert also known as Pavarotti’s solar eclipse concert.
A stamp picturing Pavarotti was also issued in Romania to mark this occasion.
Here is Pavarotti singing “O sole mio“ from that concert! It’s only natural that he sang that song! I’m afraid I haven’t found any more clips on YouTube from that concert!
