Olly Stanley Murs, Craig Ashley David and Christine & The Queens will all be performing at the Brit Awards Nominations Show thing on January 14.
Basically that's when all the nominees will be announced for February's annual music industry piss up. The categories and names will be called out by Emma Willis and the whole thing will be "broadcast live on an ITV primetime slot".
Let's chuck a quote in from Olly Murs himself shall we? Why not.
“I’m excited to announce I’ll be playing at the BRITs 2017 nominations launch. Make sure you tune in to ITV on Saturday January 14th! I always love playing live and this will be a great warm up for my 24HRS tour next year."
Now you may have missed the expertly-planted plug in that quote, so just to clarify: Olly Murs will be on tour next year and he'd really appreciate it if you'd buy a ticket, because that's where the money is these days and while his relatable persona means he has modest and accessible tastes, a man's got to buy hats.
