The 'When you Were Young' band are headlining the UK festival next month - their first show in Europe since they went on hiatus in January 2010 - and will reportedly use the opportunity to showcase material they have been working on by themselves.
In their time off, singer Brandon Flowers has released a solo album, drummer Ronnie Vannucci has been working on a record with his band Big Talk, while guitarist Dave Keuning and bassist Mark Stoermer have also been working on separate projects.
A source told the Daily Star newspaper: "The boys will probably have a song each. Ronnie's got his new album coming out soon and he's got a really great voice.
"But whatever Dave does I'm sure it will be something a little weirder though."
Shortly after the 'Somebody Told Me' group were announced as headlining the festival on June 24, Ronnie said the group were looking forward to playing for their English fans again.
He said: "It's been too long, friends. Feels like forever since we've seen each other and now it's time we pay a visit."
