Marcus... I have worked with a young lad who has CP and is wheelchair bound. For his 12th grade senior project, he asked me to mentor him and work with him on guitar. He wants to play some kind of bad and spends hours just training his hands and fingers to do simple chords.
As the project ran it's course, we discussed lots of things on guitars, and eventually got around to song writing and recording. He played a song for me that he had written. I helped him work out the parts and one Saturday, his father brought him to my studio and carried him up the steps so he could see the studio and sing his song.
Here are the results with him singing>>>
