"That was such a special moment to be able to sing that song to a group of English people in that special place," Williams told Moana Maniapoto on Te Ao with Moana.
Williams comes from an artistic and musical background. His dad David, a librarian and musician, and mum Jenny Rendall, a visual artist. Williams is of Ngāi Tahu and Ngāi Tai descent.
"Dad was the only Māori in a punk band," Williams laughs. "He had a pink Mohawk."
Williams learned guitar at Christchurch Boys' High school, where he was in a choir and initially wanted to be an opera singer and trained under the much acclaimed Dame Malvina Major.
But the lure of live music in the pub scene drew him closer.
"You play a show, and count up the cash at the end of a night," said Williams, who admits Elvis, as much as Hank Williams were big influences in his musical upbringing.
Coming from a small family, Williams had plenty of big brother figures in his life.
"I'm an only child and have had plenty of big brother figures in my life," he said.
"When I'm singing, I'm playing a role. Songwriting is acting, its posturing.
"When you write about historical people like Te Rauparaha, you are addressing another character."
It's Williams' songwriting that is now taking centre stage. His ballads are deeply personal and moving.
"People think about themselves when they listen to songs."
Based in Melbourne, Williams trajectory is certainly lighting up like a shooting star.
He's hoping his new album My Boy, due for release September 9, 2022, takes fans on another emotional journey.
