BIFFY Clyro are to headline the Reading and Leeds festivals after American rockers Queens Of The Stone Age pulled out.
The US band said they had to cancel because of "restrictions and logistics".
Ayrshire's Biffy will now join the bill, which also features acts including Liam Gallagher, Disclosure, Catfish & The Bottlemen, Post Malone and Stormzy.
Inhaler, Russ Millions and Holly Humberstone have also been added to the line-up of the English festivals over the August bank holiday weekend.
Biffy's headline slot comes four years after they last topped the bill and they're expected to perform hits from across their catalogue, including their latest album A Celebration Of Endings.
The band said: "We are delighted and honoured to be headlining Reading & Leeds for a third time.
"We cannot wait to get out there and play for you all again after such a tough year... It's gonna f***!!"

It has been reported that England is expected to open its borders to allow US and EU travellers who are fully vaccinated against coronavirus to enter without the need to quarantine, which could simplify logistics for music festivals with international acts on the bill.
American rappers Post Malone and Machine Gun Kelly, and Australian musician The Kid Laroi are among the performers due to travel to the UK for the festival.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
