Thank you for sharing this.
Tannhauser.
The Pilgrim's Chorus is one of my favorite piece. Hearing it for the first time in What's Opera, Doc? (Kill the Wabbit) was what got me interested in opera.
The Kill the Wabbit part is Ride of the Valkyries. The Pilgrim's Chorus is the love song; it starts when Bugs rides in on a fat horse.
This is brilliant, and I realise that I hadn't listened to this in an absolute age.
