Mumford & Sons Bassist Is Hospitalized The bassist for the folk-rock band Mumford & Sons has been hospitalized with a blood clot in his brain that will require surgery, the band announced on its Web site on Tuesday. The bass player, Ted Dwane, had been feeling unwell for several days and went to a hospital on Monday, where "scans revealed a blood clot on the surface of his brain that requires an operation," the statement said. "We are being assured that he will recover quickly from surgery," it said. It was unclear where Mr. Dwane was receiving treatment. The band postponed shows in Dallas, outside Houston and New Orleans. No other cancellations were announced. Mumford & Sons's latest album, "Babel," sold more than 600,000 copies in its first week and won album of the year at the Grammy Awards in February.
