Hey,
Well the meet and greet was pretty straight forward.
Just get their before the time it says,get your wristbands from the box office(Careful,they're crap paper) and wait till whatever time the sign says(There was a piece of paper in Manc. that said about it) and you'll all get took in and told to make a queue. Then you'll go through, meet the band at a table,they have posters promoting the tour that they sign so don't worry if you've not brought anything. The assistant guy there will take your camera from you and take your photo.
Then you just wait in the venue till dorrs open etc.
Any more questions,just ask.
