They have been described as the hottest ticket in Ireland and, after an impromptu performance in a Londonderry pub in February, Kingfishr are back – this time to sing to thousands.

The Limerick indie-folk group will perform at Live at the Square in Ebrington on Monday evening in front of around six thousand fans.

Members Eddie Keogh, Eoghan ‘McGoo’ McGrath and Eoin ‘Fitz’ Fitzgibbon – have emerged as one of the top Irish bands in recent years and their popularity is growing.

They topped the Irish charts on three separate occasions last year with their hit viral track, Killeagh.

They were in for a quiet pint in a local pub Peadar O’Donnell’s in Derry in February and were urged to sing Killeagh, the song which has become an anthem for fans.

It was described as “an amazing moment” by one fan. Many pub goers had their phones on hand to capture the performance.

Lead singer Eddie Keogh also posed for photos with delighted fans and pub staff.
