Colonel of Truth
Great story behind Carlos at woodstock. He did some peyote/mescaline and the called for the band to come onstage 4 hours early. He was not where he wanted to be with his trip, he was in the heart of it instead of starting to come down. Great story, I wish I could recall the descriptions of what the guitar neck felt like to him while tripping. It was basically like he was having the feeling that he had to hang on to the neck because it felt like it was taking on different forms in his hands.
He was quoted in a recent interview as saying the neck of his guitar turned into a snake, and that if he could just keep that snake under control, he'd be OK.
After Woodstock, he also was quoted as saying that "Once you play Woodstock on acid, everything else is a piece of cake."
I guess he was right...
