 I really try to listen to other recordings and play along with their records at the time. And I always like to be prepared. Well, yeah, I mean, you got to. And that's what I was going to ask you. That's how you get prepared. Now, who did you think was, of all the people you've played with, and you've played with quite a list, and you mentioned a few of them right there, who was the one that you said, I can't believe I'm sitting here playing with this person?
