Have to add a bit about Glasgow and safety
My brother has lived there for 19 years, lives quite central and has never had any bother.
Glasgow has it's good areas and it's not so good areas, but as long as you are sensible, you'll be fine.
Sheena, behave yourself.
Now, next thing, I have to check re the football for that day. I am a fully paid up member of the Scotland Travel Club (football supporters), and if they are playing at home that day, I will defo be at the the match, so will end up at the concert in my Scotland top!
