Fleetwood Mac's Stevie Nicks and Neil Finn, also the singer of Crowded House, have paid tribute to bandmate Christine McVie, who has died after a short illness.
Finn, who joined Fleetwood Mac in 2018 and performed with the iconic band on a world tour, said on Instagram it was "a very sad day."
"It's a very sad day. Christine McVie was a unique and soulful woman, supremely gifted songwriter and a warm and wonderful friend.
"I am so grateful to have shared some hours in her beautiful presence," he said.
In 2020, Finn teamed up with Nicks, McVie and fellow Fleetwood Mac bandmate Mike Campbell to record a song which was donated to the Auckland City Mission.
Meanwhile, Nicks - Fleetwood Mac's lead vocalist - shared a heartbreaking handwritten tribute to McVie on her Instagram.
Nicks, 74, said she was devastated to have lost her "best friend in the whole world."
"A few hours ago I was told that my best friend in the whole world since the first day of 1975, had passed away.
"I didn't even know she was ill... until late Saturday night. I wanted to be in London; I wanted to get to London - but we were told to wait.
"So since Saturday, one song has been swirling around in my head, over and over and over.
"I thought I might possibly get to sing it to her, and so, I'm singing it to her now.
"I always knew I would need these words one day (written by the ladies Haim)," she wrote.
"It's all I can do now…"
She then shared the lyrics to HAIM's song, 'Hallelujah'.
"I had a best friend but she has come to pass, One I wish I could see now, You always remind me that memories will last. These arms reach out. You were there to protect me like a shield. Long hair running with me through the field. Everywhere you've been with me all along," she wrote.
"See you on the other side my love, Don't forget me, Always, Stevie."
McVie was the British singer-songwriter behind some of the bands' biggest hits including 'Little Lies', 'Everywhere', 'Don't Stop', 'Say You Love Me', and 'Songbird'.
A statement from her family said she died peacefully at a hospital on Wednesday surrounded by her loved ones.
"We would like everyone to keep Christine in their hearts and remember the life of an incredible human being, and revered musician who was loved universally," the statement said.
Fleetwood Mac also posted a statement on its social media, saying there were "no words to describe our sadness at the passing of Christine McVie."
