gackt_army | R&RII - Gackt & YOU violin duet (Reply)

When I heard it first, I was just shocked and couldn't think about anything, but later I thought that the piece they played seemed familiar to me somehow... maybe some classic? So I made some research, and thanks to my mother I finally found out what they play on the concert.

I'm pretty sure that it's "Le Cygne" ("The Swan") by Camille Saint-Saëns, but re-arranged for two violins... and not the whole thing - first part (about 1 minute), which YOU-kun plays alone, and then last part (about 1 minute and a half) which they play together.

So now I'm thinking about The Dying Swan and how it fits Sayonara and the whole R&R story... let's think together?
