The Frames and Swell Season singer – who is about to release his first solo album, as revealed exclusively earlier today by Hot Press – has been added to the list of panellists for Sunday. More details will be released tomorrow.

Sunday already sees a huge number of major attractions at the event, which will draw Irish musicians and music fans in their thousands over the weekend. The President of Ireland Michael D.Higgins will speak on Sunday before a panel on Activism in Music. Brendan Graham – the hugely successful co-writer of the 'You Raise Me Up' – will talk about songwriting and Brian Kennedy and Eimear Quinn will perform special pieces, while Scottish chanteuse Eddi Reader will also speak on what promises to be a fascinating and entertaining panel.

On the live stage, Lisa Hannigan is among the key attractions in a star-studded Sunday bill, which also includes the legendary Whipping Boy, and trad superstar Sharon Shannon, while AC/DC drummer Chris Slade will give a drumming masterclass.
