So my fellow intern from this summer in Paris named Cyn waited until after I came back to the States to tell me that she could sing and to share this video with me! Haha. Perhaps she was too shy to bring it up while I was there, but I'm glad that she told me nonetheless. She emailed this link to me almost a month ago and for some reason I just got around to watching it today. (Sorry!)
From the little bit here and there that I heard her speak English I could tell that she spoke very well, so it's no surprise to me that she also sings without an accent. She and her boyfriend haven't uploaded in about a year, but what they've got up are a number of moving covers of songs that (I'll admit) I've never heard of. Below is the particular cover that she shared with me, which was also the very first video that they did.
