Metallica's James Hetfield 'Livid' Over Grammys Glitch

Metallica drummer Lars Ulrich says lead singer James Hetfield was "livid" over the technical mishap that left him without a working microphone for the band's Grammy duet with Lady Gaga.

Hetfield's verses weren't audible for the first half of the Sunday performance of "Moth Into Flame." He eventually moved over to share Gaga's microphone for the remainder of the song.

Ulrich told Grammy host James Corden on Corden's The Late Late Show on Wednesday that Hetfield was furious about the snafu. He said Hetfield is normally a "chill guy," but it "was not a lot of fun" in the dressing room after the set.

Ulrich said the band "fought through it" and some people told him afterward that even with the mistake, the performance was "great television."

Grammy producer Ken Ehrlich has since apologized for the glitch. "These kinds of things are horrible when they happen," Ehrlich said in an interview with the AP on Wednesday. "That's one of the risks of live television."
