Horslips are playing St Columb’s Hall in Derry on March 14, 2020.
There has been huge interest in the concert by fans who have been scrambling to get tickets.
As a result, organisers have warned that some unscrupulous people are peddling fake tickets for the gig.
St Columb’s Hall has posted on Facebook: “Just a note of caution.
“We have removed a number of posts from this event page from fake accounts purporting to be selling tickets for Horslips at St Columb’s Hall.
“We would strongly advise fans not to buy tickets from any unauthorised re-sellers as there is a good chance these “tickets” will be fakes.
“And as all tickets will be scanned on the night, they may not be valid for entry.
“For more advice see ticketmaster.ie”.
