I've always wanted to show MLP characters singing duets from operas that I really like. For this one I chose the love duet from Act 3 of Gaetono Donizetti's operatic rom com "Don Pasquale". In this song, the two young lovers Ernesto and Norina sneak out into the garden in the middle of the night for a secret meeting.

Here is the translation of the lyrics.
Turn to me and tell me you love me
Tell me that you are mine
When you call me your beloved
Life redoubles in me.

Your voice, so dear,
Revives the oppressed heart:
Safe while close to you,
I tremble when far from you
