Ok, understood, hope the information is found out soon!!... based on a few reports in the Irish media today (yesterday) there does appear to be at least a second show being scheduled for Dublin for the 23rd. Based on my location in Canada, IF there is WAS NOT a short presale window and tickets for the second show go on at that same time (or slightly after the first show sells out) I would be looking at another 2:00am purchase time.
GA - Vancouver, Seattle, Dallas, Toronto, Dublin ... see you on the road!
