Dvorak's 'Song to the Moon'.

 My Eyes set famished Skies to your forehead's moon
& you, chanson de l'adieu to my every tune

What betides your yet loosening hair?

    Ptolemy of Tides- I'm unaware.

Surely the loveliest video ever aired on the late lamented Sky Classical Music channel?

This is in Anna Netrebko's own voice (the previous video features the voice of Renee Fleming.)
