Yes, the "bedroom window" song has most of the same lyrics I am acquainted with. I think the Ian and Sylvia version began with "Awake, awake, you drowsy sleeper. How (why?) is it that you slumber so? For your true love stands by your window..." and there the memory gets a bit fuzzy. But I am certain that the tune they used was rather different and, truth is, I like it better. I think of it as being among the better "silver dagger" songs.
