However, I forgot that with my kids in the audience, there were at least two other things I hadn't considered that could go wrong. And Nicholas turned out be one of them. Hilariously so, as it happens. Picture this:
I've just finished my opening song, "Joy in the Journey". As the final note dies away, there's a hush over the auditorium. And into that silence pipes up an eager little voice from the front row:
"Well... you did your thing!"
Why yes, my kid watches American Idol, how could you tell?
Anyway, I had to work hard to keep a straight face for about a minute after that. My only consolation is that the lack of reaction from most of the audience would suggest they either couldn't make out what Nicholas said, or else didn't get the reference...
