"It was amazing," he told host Jimmy Fallon of the star-studded service. "I must admit: I've been to several funerals, and I've always kind of felt for the person who has to sing. I've always said, 'Oh, how do you do that?'"

Jackman also revealed that the idea of him performing at the funeral was Rivers,' which she wanted after seeing him in Broadway's 'The Boy from Oz' nearly 10 years ago.

"At her funeral, when Joan Rivers asks you [to perform], just answer," he explained. "She had planned everything out. She had seen me in a show called The Boy from Oz, which I did here on Broadway. And I sang a song from that. It was called 'Quiet Please, There's A Lady On Stage.' It's a beautiful celebration of a woman, and it was for her."
