It's approximately enjoying it – you're performing at Wembley in front of 10,000 people on the biggest show on TV, so you've just received to go out there & enjoy it, embrace it, have a satisfactory time.

"We've become better friends because we've needed each other more. It's tougher presenting the main show & we've had more stuff to deal with so we've been there for each other, which is really nice."
