"We're working on one thing with a kind of hero of ours," hints Jack Savidge, one third of dance-pop trio, the Friendly Fires.
Speaking behind the Red Bull Studio Live stage at Rockness, the drummer suggests there is some exciting news on the way for fans of the band: "We can't say who it is yet. You can't really let these things come out in the open before they are actually finalised because, if they don't work out, then you look like an idiot.
"It's one guy and he's male."
The Friendly Fires, who blur the lines between indie and dance music, put on an energetic upbeat show at RockNess on Sunday night when they performed on the main stage.

Hailing from St Albans in Hertfordshire, they were nominated for the Mercury Music prize for their debut eponymous album, and last year they released their second album Pala to great reviews.
Their RockNess performance included some notably 'groovy' dance moves from lead singer Ed Macfarlane, who also jumped into the crowd to sing - without missing a breath - before dozens of security people dragged him back over the fence.
Jack explains: "Our shows are always a bit of a voyage of discovery, there's quite a bit of room for improvising stuff a little bit."
