Good walking boots, worn in beforehand, decent dry socks, a fold up chair to sit if it's wet. I also take thermal long johns and a thermal vest because even in summer the temperature can drop at night. Don't rush and feel you have to do it all. From time to time you may want to go your separate ways but arrange meeting places and times to link back up.
Simple Minds is a difficult one, they are 1 band that I've had no interest in.
On initial announcement I thought barn headliner, but realistically no idea where they would be.
