Grammys 2017: All you need to know

The cream of the music world will be attending the ceremony 

From Beyonce's baby bump to Katy Perry's comeback, this year's Grammys ceremony looks rich with promise.

Here's everything you need to know about the show.

WHO'S PERFORMING?

 The show has a line-up to rival Glastonbury. Here's what to expect.

• Katy Perry: Giving the first performance of her comeback song Chained To The Rhythm.
• Beyonce: Not officially confirmed - but her dad says she's performing, so it must be true.
• Adele: Likely to be singing her current single, Water Under The Bridge.
• The Weeknd and Daft Punk: This is Daft Punk's first performance in three years. Will White House press secretary Sean Spicer be more impressed than last time?
• Chance The Rapper
• Alicia Keys and Maren Morris
• Bruno Mars: Appearing with Prince's side-project The Time, whose music inspired Uptown Funk.
• Little Big Town, Demi Lovato, Andra Day and Tori Kelly: Performing a tribute to the Bee Gees. Let's hope it's not as excruciating as it sounds.
• Lady Gaga and Metallica: Strange though this collaboration sounds, Gaga used to be the singer in a Led Zeppelin tribute band, so it could just work.
• Sturgill Simpson
• Lukas Graham
• John Legend and Cynthia Erivo: Performing a memorial to musicians who have died in the past year.
• Anderson .Paak and A Tribe Called Quest
• Keith Urban and Carrie Underwood
• Kelsea Ballerini
• William Bell and Gary Clark Jr

Other performers are likely to be announced in the run-up to the show, and there are usually a few surprises on the night itself.

WHO'S NOMINATED?

There are 83 categories at the Grammys - including "best surround sound album" and "best notes" (C# is our favourite) - so if you're a musician and you don't get a prize, it's probably best to cut your losses and take up ostrich farming.
You can see the main nominees at the bottom of this page, or read the full, exhaustive list on the official website of the Grammy Awards.

WHO'LL WIN THE BIG PRIZES?

 

The big fight is between Adele and Beyonce, who go head to head in the three main categories: Album of the year, record of the year and song of the year.

We predict Beyonce's politically-charged Lemonade will take the honours for album of the year; while Adele's Hello will take the others, which focus more on songcraft.

If we're right, it will be the first time Beyonce's won the main prize. Two years ago, she lost album of the year to Beck's Morning Phase, prompting Kanye West to throw all his toys out of the pram
