I did once shatter a chandelier. I was singing with my college choir in Wales. I was the soloist and I hit the high note and there was this massive bang and all this glass came down from the ceiling. I'd like that to be my party trick if I can perfect it.
I imagined that it might be awkward to talk to your wife about her performance, so going into it I was a little nervous. But doing it was actually a wonderfully inspiring experience.
