Calvin Klein or M&S?
Yes, you did read the post headline correctly. MeisterMole has tweeted the news that Bryn Terfel will be answering the best tweeted question after Wednesday's rehearsals. So if you want to ask Bryn about his pants you're welcome to try. If you want to know something else, perhaps his vest or socks situation you may stand a better chance of getting a reply.
Personally I think something opera related would be a safer bet - maybe even something about Meistersinger? You can either tweet your questions to @MeisterMole - or #askbryn. Remember - you only have until Wednesday. And hands of Bryn's pants - that question's mine.
***** Update *****
A bit more (coherent) information for you all, including an extra way to get in touch with Bryn's Inquisitors as nabbed from a WNO Facebook message...
"This Wednesday, Bryn Terfel will be interviewed for wno.org.uk during rehearsals from Die Meistersinger von Nurnberg.
Is there a question you would like to ask him? Send your suggested questions to email@example.com. Bryn will be asked the best question suggested."
