Eighties pop sensation Bros have cancelled their Wednesday gig at Live at the Marquee in Cork citing "transport/logistical" issues.
The English group, made up of twin brothers Matt and Luke Goss, were due to play at the Cork venue this Wednesday, June 26.
Their Belfast gig at Botanic Gardens will still go ahead as planned on the following day, Thursday, June 27.
A statement from organisers Aiken Promotions said: "Regretfully, Bros Management and Aiken Promotions have been forced to cancel the first of the two upcoming Bros shows in Ireland (Live at the Marquee in Cork) on June 26th due to transport/logistical issues.
"Matt and Luke would like to apologise to their fans for any inconvenience caused.
"Refunds will be available from point of purchase.
"The Botanic Gardens show in Belfast on Thursday 27th June will not be affected."
The When Will I Be Famous hitmakers, who shot to fame in the late 1980s, last played Ireland when they performed at the newly-opened Point Depot in Dublin in 1988.
Brothers Matt and Luke Goss sold out two O2 London Arena shows last year after almost 30 years apart pursuing solo careers.
Prior to the O2 concerts, they had not played together since Wembley Stadium on August 19, 1989 when they performed to 77,000 fans.
