Mumford & Sons had to postpone tour dates this week due to a medical emergency involving member Ted Dwayne, who has a blood clot near his brain. The band said on its web site: “Our friend and bandmate Ted has been feeling unwell for a few days, and yesterday he was taken to a hospital to receive emergency treatment. The scans revealed a blood clot on the surface of his brain that requires an operation. Ted is receiving excellent care and we are being assured that he will recover quickly from surgery.” “Sadly we have to postpone three upcoming headline shows planned for this week in Dallas on Tuesday 6/11, Woodlands on Wednesday 6/12, and New Orleans on Thursday 6/13. All dates will be rescheduled and will be announced as soon as we can; all tickets for this week’s events will be honoured at their rescheduled dates. We have no plans to cancel or postpone any other appearances along this current tour.” “We’re all wishing Ted a speedy recovery” the band said. Mumford & Sons has upcoming dates this month at Bonnaroo and the Telluride Bluegrass Festival.
