To take advantage of the pre sales click here. Pre sales will start at 10.00am local time for each venue.
Pre sales for the remaining shows will be announced shortly. For full Crowded House tour dates, further pre sale information and more information go to www.crowdedhouse.com or join the mailing list.
Of course, they're a bit disorganized so you have to keep your eyes open. I didn't get that email until several hours after the Chicago presale had sold out. Luckily someone on Next Exit forwarded theirs.
