John Travolta, Gareth Gates, Ricky Gervais, Macy Gray.

Ricky Gervais? On Jonathan's show? That must have taken some serious negotiating - or maybe just a kiss. I'm amazed to see Gareth Gates on the show; I thought he was happy and comfortable in obscurity. I guess he couldn't say no (that's cruel I know). Completing the guest list are full-time pilot and part-time actor John Travolta and Macy Gray, who is a dead ringer for that bear from The Hair Bear Bunch.
