A Friend of Mine is Going Blind

Do any of you know who wrote the song..."A Friend of Mine is Going Blind"? (At least I think that that is the title, I know those are part of the lyrics) Michael sang it last night at the Cafe Carpe and it was great! Now it is killing me that I can't remember who originally did it. I can even hear the singers voice, and I'm thinking it was done in the middle or late 70's. Anyone know?
