It was hardly a secret show! Manchester Orchestra had a slot on the Carling Stage on the Saturday and Jesse, Brian and Kevin Devine stood at the side of the stage watching them. At the climax of My Name Is Jonas, Jesse and Kevin walked on stage, and Jesse sang with Andy (the Manchester Orchestra lead) for a bit. It was very special, but by no means a secret show.
Yeah that's true but if you look at the photo of the performance talked about in this news story it says 'Nokia' in the background and that wasn't the case on the carling stage at the weekend.
Either way gutted I missed this if I did.
