Classical Music Arrangements in Larva [0/5 FOUND]

[CadoogenTunes]

I've been doing music breakdowns for this show, and there are some that incorporate classical music. Since music identifiers weren't able to find anything, I'm wondering if anyone can identify the exact arrangements used [Or the very least the library]
Here's the episodes that feature these tracks

Moonlight Waltz [Uses "The Blue Danube"]

Chili Show [Uses "La Brindisi", otherwise known as "Drinking Song"]

Swan Lake [Pretty self explantory]

Opera [Uses "Les Toredors"]

Cancan [Also self explantory]
