"It's just this incredible talent was there that kept him really bright and bouncy… I'm sure on his own, and a lot of times on his own, that wasn't there. I think being around people … I don’t even think it was even performing at times … I think it was just some wondrous moment, as this stuff poured out of him, he was exhilarated by it as much as we were, and I think that was so important to Robin. And at the same time, he was one of the sweetest people ever walking the planet. He really cared about people. That's what I found amazing to be able to see an incredibly huge and complex vision of the world, and yet always, all the individual around him, he was in touch with all the time."
