I was planning to go to both Amsterdam shows, but accidentally bought two different tickets (standing and seating) for the same night... Hope to swop my night 2 GA ticket for night 1.
Amsterdam I and II for the time being. Not sure I'd be able to leave wife & kid for a third show... but, when Amsterdam III and maybe IV will be announced (because they will), I'll give it some thought.
Stockholm I and II. I hope there'll be more gigs in Stockholm, then I'll try to go to those as well. I can't really commit to gigs that involve more travelling at the moment, but hopefully I will be able to some time next year and hopefully still be able to find some tickets then.
Dublin (when it's announced - hopefully most shows, 2 at least for sure)
Barcelona 1 (for sure)
Barcelona 2 (if I find a cheap ticket while being there)
Barcelona 3 (when it's announced, if it's consecutive nights, and same as above)
Maybe Paris (if there are any cheap tickets available for General sale)
Maybe Amsterdam (if Remy buys me a ticket for free )
