James Hetfield, guitarist and lead singer of Metallica, was briefly hospitalized in Sweden on Sunday, forcing the band to cancel a concert in Stockholm at the last minute, reports the Associated Press. A spokeswoman for the band told the AP that Hetfield caught a stomach bug and was admitted to the hospital for dehydration. Although the rocker checked out that night, bandmates Lars Ulrich, Robert Trujillo, and Kirk Hammett told a crowd of 16,000 fans they could not put on their scheduled concert. Ulrich told the audience at the Stockholm Globe Arena that the band was “truly, truly, truly sorry.”
