This version should fit well to the song version on the DVD. (Not perfectly, as they don´t sing quite accurate - line "now ... expectation" has a heavy difference between choir and organ)
To line "thou ... from high above": Lyrics pages in the internet say "gazed", but I think I can clearly hear the "mest" sound, and "camest" makes sense to me.
To line "... from thy nose": Lyrics pages say "emerged", but I think I can hear a "th" at the end of the word (yet tricky to hear, as the following word begins with "f" ), and as the whole piece is heavy in Middle English, I decided for "emergeth".
