Catfish And The Bottlemen have cancelled a gig at the last minute because of illness just days after fans expressed fear that their 'ambitious' concert at Tottenham Hotspur Stadium would be overshadowed by Oasis' gig on the same day.
MCD Productions posted a statement from the Welsh band just after 6.45pm on Saturday, about 15 minutes before doors were due to open at the RDS Simmonscourt venue in Dublin.
The band said: 'We regret to inform you that tonight's show is cancelled due to artist illness.
'Refunds are available from point of purchase. Apologies to all the fans who have travelled to the show today and for any inconvenience caused.'
The post did not specify the illness or who was unwell.
Fans worry that Oasis' comeback could spell bad news for the Catfish who also announced an arena tour this month which some fans now believe will sell 'negative tickets.'
The band, whose most famous song Cocoon was released 10 years ago, recently played Reading and Leeds festival as part of their comeback trail, which will culminate with a new album and a string of dates at arenas next year.
Catfish are set to play at the Tottenham Hotspur Stadium on August 3 next summer, but the show now coincides with one of Oasis' comeback gigs, just 12 miles away at Wembley.
Even before the Gallaghers' announcement, tickets were not exactly flying off the shelves for the Catfish show.
They have previously won BBC Music Introducing's artist of the year, and in 2016 took the Brit Award for best British breakthrough act.
Catfish And The Bottlemen are due to travel to Australia and New Zealand in September for several tour dates, before playing shows in the US throughout October and November.
