can't find the original post about Woodstock versions, but I may as well add that I wrote a song from reharmonizing 'Woodstock' and incorporating some of JM's lyrics.
You find interesting/convincing chords that fit the old melody, then make up a new melody based on the new chords. In this case I also used or altered some of JM's gorgeous endrhyme lyrics, which aficionados will recognize. In performance I plug in a verse/chorus from JM, which is startling and fresh because of the new harmony. "I'm the Song" Like a horse along the road shedding the weight and bridle I'm the song slipped from the case while your guitar was idle If you can sing yes to all that sadness I will enter you and stay all the life of my years and my days Like a fish that spawns upstream away from a sea of troubles I'm the song from the time of man when your guitar was able if you can sing yes . . . I'm the song from the time of man when your guitar was able if you can sing yes . . . [Mitchell verse/chorus] like a bird that take wing at last over the psychobabble I'm the song shot up in the sky and your guitar is liable if you can sing yes . . . * 'shot up in the sky' is my approximation of 'shotgun in the sky' which I couldn't fit gracefully.
