I recently discovered this song one day when I was listening to a Sarah Brightman mix on youtube on my phone. I listened to it once and immediately had the song stuck in my head. I have to say I'm very confused if there is a recording of Sarah singing it or not, or why both she and her sister Amelia sing it. Sort of like when Sophie was singing the same songs as Hayley at one point? LOL The only album I could find with the song is on the Gregorian album, Masters of Chant II, with Amelia singing it. Apparently she co-wrote it, so I guess it's technically her song. Their voices actually sound VERY similar (but I still prefer Sarah's). But anyway, I've had it stuck in my head all day long and doesn't seem to be on its way out anytime soon. LOL I'm kind of obsessed with at the moment. It's very catchy. Here are both ladies' versions (there are also merged videos. Also one of them singing part of it in French.
