There's nothing to outvote... if John refuses to give permission to use his voice and image, nothing gets released. About the time of the performance: they were originally scheduled to appear in the evening at around 9 or 10PM, but the whole festival was running late because of the weather and various problems, so they ended up starting at around 12:30AM. The closing performance by Jimi Hendrix was planned to take place on Sunday evening, but he could only get on stage at 9AM on Monday, when most people had already gone home (even though over 300,000 people went to Woodstock, less than 50,000 saw Hendrix perform).
