Singer-songwriter Colin Vearncombe, who performs under the stage name Black, remains in a medically induced coma in Cork University Hospital following a car crash.
The 53-year-old Liverpudlian, best known for his 1987 hit Wonderful Life, was travelling from his home in Schull, West Cork to Cork Airport last Sunday when the crash took place.
His wife Camilla and three sons are at his bedside.
"It's a waiting game," his spokesperson said.
In an update on Black's website, his management said: "Colin remains in a critical condition in hospital in Ireland. He has suffered a serious head injury and has been placed in an induced coma to allow him the best possible chance of recovery."
They continued: "He is likely to remain like this for several days but we will post an update as soon as there is any significant change in his condition. He is receiving the best possible care from the Intensive Care Unit team. Thank you to everyone who has posted, messaged, emailed and texted. Please keep doing it as his family are deeply moved and helped by your support and love."
Black has lived in Ireland for over a decade. He has released more than a dozen albums and has also published poetry and staged exhibitions of his art in Ireland.
