Traditional Irish music legends The Chieftains have been awarded honorary doctorates in recognition of their outstanding contribution to music.

Paddy Moloney, Sean Keane, Matt Molloy, Kevin Conneff and Triona Marshall were given the doctorates by the Dublin Institute of Technology for their role as cultural ambassadors.

Founding member Moloney told a graduation ceremony for music, drama and media students in St Patrick's Cathedral, Dublin: "It's wonderful for The Chieftains to be recognised individually as well as collectively with this kind of tribute."

Since they were formed more than half a century ago, they have collaborated with musicians including The Rolling Stones, Van Morrison, James Galway, Bon Iver and Imelda May.

Earlier this week they played at a tribute to Irish poet Seamus Heaney at packed Royal Festival Hall in London.
