Proof that Lincoln was a music-lover?

Good article. I remember he attended a performance of The Magic Flute near the end of his life.

Ahhh, Mozart. I did not know the Zauberflöte was among the theater performances offered in DC while the Lincolns lived there. Good to know!!
Was Lincoln's German good enough to follow the plot? (Rhetorical, of course it was not.)
