Greensleeves versions

I'm learning a nice old piece, but looks like there are some multiple versions. I've found this sheet:

But for me the C# sounds strange, and looks like there are other interpretations where it is played as C. First my version, second the one of the sheet:

You can hear my version in some YouTube videos, too:

But the second version is not bad, too, but maybe some other notes needs to be changed then, too and I guess other chords are needed.

Which one is the original? And which one do you like more? I've setup a poll, so you can vote for your favorite.

My greensleeves guitartab starts on C# ( best arrangement I've found ), not E as on the sheet. But I dont have a capo for the guitar so i'm playing it in A atm ^_^

( took a look at youtube, seems that most of the people are actually starting on A )

If your instrument is tuned in equal temperament ( http://en.wikipedia.org/wiki/Equal_temperament , I assume most pianos today are tuned in this temperament), then I think it doesn't matter where it starts, but maybe some start notes are easier to play for the fingers.

BTW: I've found another sheet, without the C#, more like I like it:
