Almost forgot this one. I"m a fan of both acts and this is the only example I can think of where the person who wrote the song admits that not only is the cover better, but that the song makes more sense when performed by the second artist. I can barely watch it, but I think the second video is possibly the most moving thing I"ve ever seen on any screen
