In 2023 Quilty invited Andy Irvine to join the band on a tour of Sweden celebrating Quilty’s 30th anniversary. Andy Irvine and Quilty now offer a concert programme consisting of both Irish and Swedish traditional music - adding a new facet to the world music influences that have been Andy Irvine’s trade mark since early 70th.

Andy Irvine is one of the great Irish singers, his voice is one of a handful of truly great ones that gets to the very soul of Ireland. He has been hailed as "a tradition in himself." Musician, singer and songwriter, Andy has maintained his highly individual performing skills throughout his over 55-year career. From Sweeney's Men in the mid 60s, to the enormous success of Planxty in the 70s, his duo with Paul Brady in the later 70s and then from Patrick Street to Mozaik, LAPD and Usher’s Island, Andy has been a world music pioneer and an icon for traditional music and musicians.

As a soloist, Andy fills the role of the archetypal troubadour with a show and a travelling lifestyle that reflect his lifelong influence, Woody Guthrie. To quote The Irish Times, "Often copied, never equalled", his repertoire consists of Irish traditional songs, dexterous Balkan dances and a compelling canon of his own self-penned songs.
