Öffne meine Augen
appears to be a German version of Open thou mine eyes
composed by John Rutter
. The version sung by the Weimar Kreuz Chor, Korea in the listed video is exactly the same as the loose sheets in my possession. I learned and sang this lovely piece as a bass singer in Die Zeitlupe
sometime in 2006. Where their leader, Jürgen Blendermann, got it - I do not know. Does anyone out there in cyberspace know?
It is listed in Geoff's Choral Odds and Ends.
