We've been through this 3 times. My DS auditioned:
- at 11 - did a little juggling / silliness routine for producers
- at 14 - ventriloquist act - for producers, then for judges round - got four No's, but positive "come back again" type feedback
- at 17 - ventriloquist act - was invited straight to judges round, got four Yes's, went to the decision day where you get filmed to see if you are through to live shows - he wasn't (last year).
Throughout, we had our eyes open. He never felt humiliated. We saw it as an opportunity to see how the business works and it was fun to be a bit "in the know" when watching back on the TV. We knew it was "fixed" in many ways - even this year he was rung a couple of days before the final judges rounds filming to day they didn't have enough variety acts, could he come along? (He didn't in the end)
It was a fabulous opportunity to people watch, and to chat to other people in the entertainment industry. The staff behind the scenes work tirelessly and were all lovely, kind, welcoming, really helpful.
If you go, do be prepared for hours of waiting around, although you will always be with your daughter as she is young. At our last trip, he was old enough to be at endless interviews and incidental filming on his own, so I spent a lot of the day sat with the couple of his friends who had gone along (who incidentally were competitors on the Voice at the same time, but it hadn't yet been screened - so they knew what to expect!).
Take plenty of your own food and drink - the venues we have been at had very little, and nothing is provided for you.
Go "all dressed up and ready to perform", don't take a chance on changing outfits once you get there. Oh, and if you have any real expectation that she will get through to the judges, go wearing clothes and with a haircut that you would be prepared to wear again a few weeks later - you are not allowed to change your appearance for the sake of continuity!
Would he do it again now? Probably not, as there is always a risk to your career that the way you are projected on TV is negative. But, TV exposure is absolutely critical to gain some leg ups in this business. He's doing OK though, at 18, is performing his own show on cruise ships, to audiences of up to 1000 at a time, leaving for the Far East in a couple of weeks, and the Caribbean shortly after that. Didn't need BGT for that!
