Stephen Cummings joins the day on the green line up with Bryan Ferry at Sirromet on March 3.
He replaces an intended performance by Died Pretty. Upcoming Died Pretty shows have been cancelled due to the ill health of singer Ron Peno, soon to commence treatment for oesophageal cancer.
Roundhouse Entertainment director Michael Newton said Peno had his full support.
"We look forward to having him on another a day on the green bill when he’s back in action,” Mr Newton said.
Ferry is also being joined by I'm Talking and Models.
Cummings' was part of day on the green's first show in Victoria in 2001. His return coincides with the release of his 20th solo album, Prisoner of Love. He is also releasing the 50-track solo anthology, A Life Is A Life in April.
Ferry's set list draws on material from a long career, including classics from Roxy Music like Love Is The Drug, Avalon, More Than This, Virginia Plain and Jealous Guy, as well as much-loved solo hits like Let’s Stick Together, Slave To Love and Don’t Stop The Dance.
