As of noon (ET) July 29, tickets were still available to Jerry Seinfeld's pre-Broadway engagement at the Civic Center in Des Moines, IA. A spokesperson at the center said there were "plenty" of tickets left to all four concerts, scheduled for 7 and 10 PM on both July 31 and Aug. 1. Seinfeld -- whose Aug. 5-9 Broadway gig sold out in less than six hours -- also failed to draw capacity audiences in Omaha on July 24 and 25, causing producers Contemporary Productions to give away 2,000 tickets at the last moment. A spokesperson at Contemporary said no tickets would be handed out for the Iowa dates.

Tickets to Seinfeld's ten Broadway concerts went on sale 10 AM July 23 and were gone by 3:30 PM, said publicist Merle Frimark's office. Demand for the comedian's Aug. 5-9 one-man Broadway engagement was so great that, before noon, a second phone line had to be created to accommodate incoming calls.

Seinfeld is preceding the New York concert series with what may amount to the most far-flung pre-Broadway tour in history. He began with a booking in Australia, where he staged a handful of June performances in Melbourne and Sydney. The globe-trotting comic followed that booking with dates in Sweden (July 3-4), Iceland (July 8-9), London (July 12) and San Antonio, TX (July 17-19) at the Majestic Theatre.
