Midge Ure has had to cancel his upcoming tour due to a health issue needing “urgent” treatment.
The Ultravox singer will perform in August but take time off from September, with shows dropped in Australia and across Europe.
Ure, 71, wrote on social media: “During a recent routine check-up, doctors discovered a health issue that requires urgent treatment and a period of recovery.”
The Scottish star, from Cambuslang near Glasgow, organised Live Aid alongside Sir Bob Geldof and had 1980s chart hits with Ultravox and Visage.
Ure said the cancelled gigs would be rescheduled for a future date.
He wrote: “I know many of you travel great distances, often across borders to attend the shows, and I never take that support for granted.
“I’m truly sorry for any inconvenience or disruption this causes to your plans.
“I remain fully committed to performing all shows currently scheduled for this month and I’m looking forward to being out there with you for as long as I’m able.”
Ure said he was aiming to be back as soon as possible and that a 2026 UK tour – titled A Man of Two Worlds – would be going ahead as planned.
A 2013 poll voted Ultravox’s 1981 single Vienna as the greatest number two hit in history, after it was kept off the top spot by novelty track Shaddup You Face by Joe Dolce.
