I'm looking for an old song. It is taught in schools as a music lesson. It is NOT a Bread song, David Gates or Elvis.
Guitar Man
He sits and strums his guitar, and weaves his thoughts into the music that he plays, people gather round to hear the magic sound, he sings a tuneful ballad from his heart. And everyone knows the guitar man will sing their troubles away, capturing hope in a melody, to ease their hearts when he begins to play. He sits and strums his guitar..

I found this song on Youtube, its written by Audrey Snyder. Here are links to a couple versions of it: http://www.youtube.com/watch?v=F1ibNaQh7Yw and http://www.youtube.com/watch?v=Sxk-e2aGsQA&feature
