I went to see Bryan Adams at the O2 on Wed 14th dec it was a great night. He is still singing as good as ever and Keith Scott what a guitarist. I noticed there was not an amp on stage not quite sure how they do that are the amps to the side and mic up or a straight DI into the sound mixing desk.
When i saw Jeff Lynne also at also the O2 i asked the sound engineer about the cabling from the mixing desk thinking there was a duct in the floor up to the stage to carry the cables he said no they had tied them to the back of the chairs and up to the stage.
