Singer Edwyn Collins is recovering from another operation stemming from his emergency brain surgery on 25 February, his wife has told fans.
Edwyn Collins had a global solo hit with A Girl Like You in 1995
A piece of his cranium replaced at the beginning of April was removed last Wednesday after the former Orange Juice frontman contracted an infection.
"He still has some infection in there which (doctors) are doing battle with," Grace Maxwell wrote on his website.
But she said his "fighting powers" were "consistently ridiculously strong".
Collins was taken to hospital on 20 February, several days after complaining of vertigo and vomiting.
The Edinburgh-born singer-songwriter then had emergency surgery after suffering a second haemorrhage.
Following his initial cranial surgery he was moved to a neurorehabilitation unit on 7 April, only to be returned to London's Royal Free Hospital the following day.
Despite this Maxwell says he is in good spirits. "He has been singing these past few days," she wrote, adding: "His tuning needs working on."
Collins led Orange Juice to a number eight UK hit with Rip It Up in 1983. His solo single A Girl Like You reached number four in 1995.
A compilation of his early songs, The Glasgow School, is due to be released in May.
