Lizzie Marvelly reveals about her worst nightmare that came true

Singer Lizzie Marvelly has opened up about her "worst nightmare" during the singing of the national anthem, saying the mishap caused her to shed a "few tears".

Marvelly was singing the anthem before the Maori All Blacks game against the touring British and Irish Lions in Rotorua on Saturday night.

The 27-year-old posted to Instagram to say a sound malfunction caused her to falter during the performance.

"So last night my worst nightmare happened," she wrote.

"We wear in-ear monitors so we can hear ourselves when we're singing at games, and last night mine failed during the song I sang before the game.

"We switched them over before the anthem, hoping that would fix the problem, but when I got out there to sing they started crackling pretty severely before they cut out entirely."

She said she couldn't hear anything and lost her place in the anthem.

She removed the ear monitors and was able to carry on, but said she felt "utterly devastated".

"Gave it everything I had to finish it off, but I felt like I'd let everyone down, and there were a few tears after."

She said event organises believed the cause of the disruption was a "frequency issue", and she had been overwhelmed by messages of support since the anthem.
