Kuroshitsuji Musical 2 English Karaoke - Alan and Eric's Themes and Duet

It has now been 11 years since I first dabbled with creating English versions of songs in other languages just because I really wanted to sing along to the music. (I spent a week wrangling every song in KuroMyu2 into shape. I never made any videos for it until now, and probably no one cares anymore, but I really wanted to put a clip up with these songs in particular.)

I just really like the way Eric and Alan each have their own theme songs, introduced earlier in the musical, which at the end are revealed to be two halves of a counterpoint duet. They were meant to go together all along.

Alan's Theme - Sei to Shi no Sukima (The Crevice Between Life and Death)
Eric's Theme - Hanakotoba wa "Kodoku" (The Flower's Meaning is "Loneliness")
Alan and Eric's Theme - Unmei (Fate)
