The British folk stars were due to perform at the Montrose Beach & Park venue on Wednesday (17Jun15), but consecutive days of storms disrupted work at the concert site, so the show has now been postponed to Friday (19Jun15).

A message posted on the band's page, reads, "It is with massive regret that we have to announce that tonight's headline show in Chicago has to be postponed to Friday June 19. Despite huge efforts against really unfavourable weather, the local promoters have been unable to build us a stage in time for the show tonight. It takes a lot for us to pull a show, it's something we try to avoid at all costs, but tonight it's just not going to happen. Of course we are devastated.

"We are so sorry. We are absolutely gutted and more than a little frustrated - this is our biggest ever headline show away from home, so... this one hurts the most. But Friday night is going to be all the more special for it, so we really, really hope you can make it."
