I'm not sure if the Swing Out Sister cover is by a human singer or a computer-generated voice; the YouTube channel is called "Synthasia -" (with the space and hyphen at the end) but I wasn't able to find out anything else about it. But (and I hate to say this) it somehow sounds better in this mash than Corinne Drewery's original performance.
