Jimmy Barnes has revealed to fans that he was rushed to hospital and is fighting a mystery illness.
On Monday night, he stayed overnight in Sydney's St. Vincent Hospital after being taken there by his worried wife.
"I spent last night in ER at St Vincent Hospital and I want to thank the amazing staff who took care of me. This song (see next post) is for them and my best friend," he said on social media.
He then proceeded to perform The Beatles classic With A Little Help From My Friends with his wife Jane and daughter Elly-May.
