肢体雪人案是真事儿么:下面这首歌的歌名叫什么，是谁唱的？

If rain will fall high up here upon the mountain grass will grow and shepherds will be thankful and our love will cover up for the mountain For time is like a promise it tries all your strength to keep to Before she came I lived alone upon the mountain raven heard your voice high upon the wind then one day you came to me upon the mountain For time is like a promise it tries all your strength to keep to The sun goes down and shadow sooner into weaving but she lies so deep inside my love surrounds us.. time will out-do what's this I only know too well For love is like a promise it tries all your strength to keep to If rain will fall high up here upon the mountain grass will grow and shepherds will be thankful and our love will cover up for the mountain For time is like a promise it tries all your strength to keep to
