What a fox.
Léo Delibes (1836-1892)

Chorus master, organist, and composer of the nineteenth century most famous for his operas and operettas. He inspired great composers such as Saint-Saëns and Debussy; Tchaikovsky even had a higher regard for him than he had for Brahms (which is saying something!).

Dôme Épais (The Flower Duet)

You may have heard it in movies such as Superman Returns, Tomb Raider, and True Romance. It's used in advertising, most notably for British Airways.
Really beautiful lyrics. I love this song, maaaan.
