Yeah. But it's challenging. It's challenging to them. And they don't sit bored. We try to get as many, like at least what we can. Once every two months put a new chart in. We've got four or five things right now we really haven't tried as much as we should. And Sherrie is great at it because -- Dennis Mackrel wrote a wonderful chart for us on "In a Mellow Tone," you know, the great Count Basie drummer. And we lived with it for a while, and Sherrie made some changes, and still respected what he did and it's for the better. See? It's for the better, what we do.
