All those years of Stevie introducing Rhiannon by saying, "this is a song about a Welsh witch," certainly helped perpetuate the witchy-ness. And how many stoned/drunk audience members probably heard something different, and they told 2 friends, and they tell 2 friends, and so on, and so on, and so on. And if you're as old as me, you'll know I just made a reference to that old shampoo commercial from the 70's.
