JB has a contract to fill in for McLaren when requested. He had to do it. I get the feeling JB is not that ecstatic to drive at Monaco. Happy to, but not ecstatic.
Jonathan Neale says my comments above are not true. Button is not only happy, he's also ecstatic to drive at Monaco.
It was nice to see him relaxed in the press conference. He listened intently to the other drivers too. He isn't expecting anything but he will give it hell because it's essentially his home race.
