I have never felt so touchy emotions from "Hymne à l'amour" performed by them comparing with Édith Piaf and Fubuki Koshiji (who was a Japanese singer famous by the performance of the song). However I have indeed felt so much errupotios from my heart derived by their performance of it. Since, I deem, I deeply thought about their daily efforts of tears, sometims lose hope and lose confidence, but finally they have turned into their bright smiles making every audience happy and smiles. (From Japan. I could not fully express my emotions by Engilish since it is not my mother tongue language.)
