Renaissance covers are not very common nowadays. Scroll down for a few off YouTube (and add more if you find a good one -- copy/paste the "Embed" code that's shown to the right of the video on YouTube. )
Another Ocean Gypsy cover. This one is way above average, I think, because a) it's a capella; b) the singer maintains an interesting "hurried" pacing; c) she has that mystic/hippie look that fits the song and era; d) she's a good singer. The interpretation itself is closer to the Blackmore's Night one than the original.
