First of all, very nice countdown on the Top 100 classical tunes. There's been this piece that I've been searching for that was featured in this classic cartoon. I've identified Offenbach's Orpheus in the Underworld throughout the cartoon but the piece of music I'm interested in starts at 2:10, 4:18, and again at 7:20. Thanks for the help.
