This song was used by a high school glee club/choir back in the mid 70's. The words to this song are:

"there is a voice, that has no name,
it comes with evening or behind the rain.
I have no time now, to stop and explain,
I just keep moving, cause it helps to ease the pain.
The night has music, that calls to me,
across the canyons of an endless sea.
I have no time now, to stop and explain,
I just keep moving, cause it helps to ease the pain.....".

The school orchestra also had sheet music to accompany the singers. There was a flute solo. Any help you can give in finding out who wrote this music, if there are any recordings and where I can get the sheet music(piano) Will be greatly appreciated.
