Judith Durham is unstoppable and will sing again once she has recovered from a cerebral haemorrhage, fellow Seeker Keith Potger says.
The Seekers star fell ill on Tuesday night after the band played a concert at Melbourne's Hamer Hall and was taken to hospital.
Potger visited Durham at her bedside on Thursday morning and said she was resting comfortably as the pair had a long chat.
Durham would have tests which would probably go on for about 10 days, Potger said.
"She's doing well," he told AAP.
"At this stage, I can't see anything other than a positive outcome."
The group will take a break while Durham is given all the time she needs to recuperate but will return, he said.
"Judith will be 100 per cent keen to get back on stage and perform again and we will support her all the way," he told AAP.
"She is unstoppable, that girl. She is amazing.
"She may look frail but she is absolutely one of the most resilient people that I have ever had the delight to meet and be part of my family."
Potger said the band was happy with Tuesday's performance and they all spent some time signing autographs before returning to their hotel.
Durham called Graham Simpson, the manager of her company, after she had difficulty operating a television remote.
After consulting the Nurse on Call telephone service, Mr Simpson rushed Durham to hospital, Potger said.
Durham is delighted with support from fans, he said.
"She is absolutely thrilled and very, very humbled by the whole situation and wonderfully grateful about the good wishes," Potger said.
