Description of Gounod's Faust from the Lyric Opera of Chicago's website:
Who doesn’t long to be young again? It happens for the aging philosopher Faust — he sells his soul to the devil and, in exchange, is transformed into a dashing young man. He falls in love with the innocent Marguerite, with disastrous consequences. Gounod’s masterpiece has been one of the world’s most popular operas for more than 150 years. You’ll know why when you hear the score, which simply bursts with memorable music. Marguerite’s Jewel Song, the Soldiers’ Chorus, the spectacular final trio — these and much more make Faust a sublime experience for young and old alike.
