Mumford & Sons cancel New Orleans show; bass player has blood clot

Mumford & Sons has been forced to cancel their New Orleans show because a blood clot on the brain was found in bassist Ted Dwane.

The band is also canceling shows in Dallas and Houston. The popular British folk band will make up the performance at a later date and plan on hitting the road again by June 15, according to their website.

Mumford & Sons won Album of the Year at the 55th Annual Grammy Awards for their platinum album "Babel."

The band recently made headlines with U2 front man Bono, Sting, Green Day, and Ed Sheeran. They are among other musicians raising their voices against poverty by re-recording classic protest songs.

The agit8 project, which hopes to influence leaders at next week's G-8 summit in Northern Ireland, is backed by the One Campaign set up by Bono.

It wants G-8 leaders to help boost African food production and improve transparency in international aid.

The band posted this message on their website about Dwane:

"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.
