My sister went. What surprised her was that all of the Idols acted exactly the same as on the show. Dave looked bigger in real life than on the show. Dominic Bowden was MC, and acted more natural than on the show. Paul Ellis made an appearance at the end of the show. My sister only went because she fancies Michael, so she was stoked when he sang "I'm singing this song especially for you" and pointed at her! She also got a special wave from him at the end.

All the idols didn't go Duckies, because Paul Ellis picked who went on tour and who doesn't and that if anyone caught the idol show, where they shwed what they would be doing on tour would have heard Dom say it on the program.
