John Brower:

"When Morrison and the Doors heard that Lennon was now going to play, he asked [Doors manager] Bill Siddons to set up a meeting to discuss who would headline the show. There was a knock on the locker room door and it was Bill [Siddons] and Morrison asking if they could talk to John and me. I grabbed John and we met in the hallway. The two singers didn’t acknowledge each other or shake hands but Siddons wanted to ask Lennon if the Doors could go on before Lennon*.* John’s eyes opened wide and he said, “No, you guys are the headliners. That means you go on last, that’s the way it works.” John was not about to be upstaged by Morrison and whatever antics he might pull off. Just then, Little Richard appeared, and said to us, “Hey, I will headline! I will headline!” I then told Morrison, “Look, I have already paid you guys, so if you don’t want to play, you can go back to your hotel room and relax. No problem.” Morrison nodded at Siddons and they agreed to go on after Lennon. Then Morrison said, “One thing: We want to be on the side of the stage so we can watch the set.”
