Sinéad O’Connor has received an incredible show of love among a host of tributes that poured in following the news of her death yesterday.

Artists from across the musical spectrum, writers, actors, sportspeople and other celebrities shared their admiration for the much-adored yet polarizing singer, who passed away at the age of 56.

Although the tragic news hit some "like a train", nobody was lost for words when it came to describing the beloved "voice of Ireland".

Writer Bonnie Greer described O’Connor - who gained international stardom and applause for her cover of the Prince song Nothing Compares 2 U - as having a great soul music voice.

She tweeted: “Soul music is not about ‘ooh, baby, baby’. And I know about soul music because I was born and grew up around where Sam Cooke sang… and #Prince knew that #Sinead had it in her, too – that’s why she got his song.

“But her voice was #Ireland right down to the ground.”

Voice of an angel

Irish MMA superstar Conor McGregor, who had O'Connor perform at one of his fights in 2015, initially said he was 'gutted' to hear the news, before later saying: "The world has lost an artist with the voice of an Angel. Ireland has lost an iconic voice and one of our absolute finest, by a long shot. And I have lost a friend.

"Sinead’s music will live on and continue to inspire! Rest In Peace, Sinead you are home with your son I am sure."

The Irish author Marian Keyes described the news as “heartbreaking”, describing the singer as an “amazing, brave, beautiful, unique wonder”, while writer Caitlin Moran said O’Connor was “THE greatest voice of her generation, no contest” and “fearless”.

Perhaps the most poignant tribute came from Victoria Mary Clarke, the wife of The Pogues star Shane MacGowan who was for a time great friends with O'Connor.

She thanked O’Connor for her “love and friendship”, possibly referring to saving MacGowan from addiction in the 1990's.

No words

Posting a photo on Twitter of MacGowan and O’Connor together from their younger years, she wrote: “We don’t really have words for this but we want to thank you Sinead.

“For your love and your friendship and your compassion and your humour and your incredible music.

“We pray that you are at peace now with your beautiful boy. Love Victoria and Shane.”

Clarke, who retweeted a picture of the singer and her son Shane who died last year, also remembered her as “incredibly funny” in a second post.

“She told outrageous jokes at the most inappropriate times and she cracked me up! There will never be anyone even remotely like her,” she added.

The singer Cat Stevens, who like O’Connor converted to Islam, said “she was a tender soul”, while singer-songwriter Billy Bragg described her as “braver than brave”.

Smashing Pumpkins singer Billy Corgan posted on Instagram, saying she was “fiercely honest and sweet and funny.

He wrote: “She was talented in ways I’m not sure she completely understood. But Sinead stands alone as a figure from our generation who was always true to the piercing voice within and without. And for that I will always admire and respect her.

She stood for something… Unlike most people

“And never forget that she was once cancelled for an act of simple resistance. Her crime? Tearing up a photo.”

Rapper turned actor Ice T tweeted: “Respect to Sinead….. She stood for something… Unlike most people”, while American singer-songwriter Jason Isbell posted: “I hope there’s peace for Sinead at last.”

Among other musicians to post tributes were Belinda Carlisle, Janelle Monae, UB40, Melissa Etheridge, Margo Price and Rage Against The Machine guitarist Tom Morello.

Irish comedian Dara O’Briain said he hoped the singer “realised how much love there was for her”.

Actor Mayim Bialik said “her music changed the industry”, adding O’Connor’s “fierce fearlessness made a tremendous impression” on her as a teenager.

Oscar winner Russell Crowe shared a story about meeting her while working in Ireland last year and enjoying a conversation outside a pub.

He wrote: “In a conversation without fences we roamed through the recent Dublin heatwave, local politics, American politics, the ongoing fight for indigenous recognition in many places, but particularly in Australia, her warm memory of New Zealand, faith, music, movies and her brother the writer.

“I had the opportunity to tell her she was a hero of mine.

“What an amazing woman. Peace be with your courageous heart Sinéad.”
