Thanks guys, much appreciated! I too figured since F is natural in the previous bar that we go back to F sharp for the next bar, only problem was it was now showing the D as being sharp as well and when I played the combination I was like, this sounds very weird and there is no place in the song that sounds like this, so something had to be wrong. Of course the next question was, do I play the F natural and the D sharp or what? I tried a few different combinations and it didn't sound right until I went F#, D natural and A natural. So, I figured the # marking was just a reminder to go back to F sharp and the D was to be natural, it's just that it was marked incorrectly on the wrong (D) line.
I kind of figured this sort of notation mistake would be slim to none, but I suppose it happens. The piece I found here has been marked up by someone along the line, you'd think they would have caught and corrected it, or at least pointed it out. Maybe they've been playing it wrong the entire time?
In any case the clarification is much appreciated and now it's back to learning this wonderful piece.
