Andy Irvine and Paul Brady have rescheduled their March shows in Belfast and Dublin to this September.
The duo's tour is to celebrate their acclaimed, self-titled album which was released in 1976. The pair first marked the album's 40th anniversary with sell-out shows in London, Prague and Dublin in 2016.
They will be accompanied by Dónal Lunny and Kevin Burke, both of whom were players on the original album, on the rescheduled dates.
All tickets for the original date will remain valid for new rescheduled shows. If you are unable to attend the new date, please contact point of purchase by March 31 for a refund.
