Good practice not to be a slave to playing open strings as that wont transpose very well.
If you play fretted, key shifts are just another position on the neck around the same shape.
For this song, most will play in the original key but if you cover a lot of music then other keys come into play.
You've heard the one about how to shut up a gtr..?? give him a horn key...
Same would apply to bass..

Fair enough. I've never really thought about it like that.
I've always played WGFA in the original key of A and as per the version above use lots of open strings - there are a few pull offs onto open strings which give the line a certain swagger. I imagine the line would stiffen up if played elsewhere on the neck.
