I just needed to share this video of Madama Butterfly. This is the great duet that ends act 1. The video itself is somewhat poor, but watchable. The performance is stellar, and worth the trouble.
The performance is from New York City Opera in 1982 with Judith Haddon as Madama Butterfly and the American tenor, Jerry Hadley, as Pinkerton.
This is a fantastic, moving performance. Their voices match each other in beauty. Just sit back and enjoy.
