LOS ANGELES — The longtime producer of the Grammy Awards is offering apologies to Metallica and Shirley Caesar after a technical glitch and a misprint marred their inclusion on the show.

The mic for Metallica’s James Hetfield wasn’t initially working when the band took the stage to perform with Lady Gaga, and Caesar, a lifetime achievement award honoree, was misidentified during the televised ceremony when a photo of another gospel star, CeCe Winans, was shown instead of her during a montage clip.

“These kinds of things are horrible when they happen,” Ken Ehrlich said in an interview on Wednesday. “That’s one of the risks of live television.”

The Metallica glitch resulted in Hetfield making a decision to improvise and use Lady Gaga’s mic.

“My guys say that the mic cable was connected,” Ehrlich said. “My guys’ theory was that ... one of the extras (on stage) accidentally kicked out the cable that went to the mic.”

“Obviously, we apologize to the band,” Ehrlich said, calling the mishap “awful.”

In the case of Caesar, the gospel legend, Ehrlich had a better understanding of what happened.

When preparing for a clip for the show, footage of a classic Caesar, Winans and Whitney Houston performance was used, and Winans was mistakenly shown.

“We obviously want to apologize to Shirley Caesar,” he said. “It’s unfortunate that happened.”
