American singer-songwriter John Prine is in a critical condition in hospital after a “sudden onset” of coronavirus symptoms, according to his family.

The 73-year-old was taken to hospital on Thursday after he experienced the symptoms of coronavirus. He was intubated on Saturday night. He has been receiving care but “his situation is critical,” his family said in a statement posted on Twitter.

“This is hard news for us to share,” the statement read. “But so many of you have loved and supported John over the years, we wanted to let you know, and give you the chance to send on more of that love and support now. And know that we love you, and John loves you.”

Fans and friends took to social media to support Prine and wish him well.

Bette Midler, who covered Prine’s song, “Hello in There,” tweeted, “One of the loveliest people I was ever lucky enough to know. He is a genius and a huge soul. Pray for him.”

Musician Keb’ Mo’ tweeted, “We are going through a time that reminds us not to take anything for granted. We tell people we love them. This one today goes out to @JohnPrineMusic as we pray for his healing.”

The two time Grammy Award-winner has had a nearly 50-year career playing a blend of country and folk music.

His songs from his 1971 debut album were later covered by musicians such as Johnny Cash, Bonnie Raitt, John Denver, and Norah Brown.

In 2009, Bob Dylan said Prine is one of his favorite songwriters.

Prine has survived cancer twice. In the 1990s, he had to under surgery to remove a tumor from his neck, which changed the tone of his voice, deepening it and making it hoarse. He also underwent surgery to remove a tumor from his left lung in 2013.
