Anyome sweating over tickets or even buying them when they go on sale need not worry.
Last time they played Heaton Park, the touts were lining up on the road where the direct busses from town were pulling up at.
Me and my (then 14 year old) daughter got off the bus and the touts approached us, all offering £40 or £45 tickets (can't recall which one) for £15 each.
Same will happen this time too. All the trendies caught up in the hype "look at me I got tickets".
Then come July they can't be arsed / booked a holiday / going to a wedding and offloading the tickets along with many others and the price tumbles.
