This year's RockNess Festival is offering one lucky person and a friend the chance to watch their favourite act from the side of the stage. The competition is open to anyone who has already purchased full weekend tickets, or day ticket holders who want to upgrade to a full weekend ticket, and will end at midnight on Thu 31 May. The winner will be contacted on Fri 1 Jun.

So fancy seeing the crowd go crazy to Deadmau5's beats on the Saturday night, or rock out on stage with Biffy Clyro (pictured) on Sunday at the festival's finale?

If you already own a full weekend ticket, just go to the RockNess website to enter.

Those wishing to upgrade their day tickets to weekenders can do so here.
