It was an opera duet cover of Duo De Fleurs (Flower Duet) I believe and the title was something like "Opera Shion and (other singer's name I forgot but feminine voice I believe) Lakme Duo De Fleurs (Flower Duet)" or something like that and it sounded very realistic. I remember 'Opera Shion' but I forgot the name of the second singer. I tried looking but it seems to be gone, somewhat irrelevant searches pop up, or I simply am using the wrong keywords?
