Ceiliúradh: Royal Albert Hall celebrates Irish culture
Artists and musicians from Ireland, as well as descendants of Irish emigrants, have performed in a London concert at the Royal Albert Hall.
The event was called Ceiliúradh, which translates as celebration.
It was held in honour of Irish President Michael D Higgins as part of the historic state visit to the UK.
Earlier on Thursday, the Queen and Mr Higgins hosted a Northern Ireland-themed reception at Windsor Castle.'Gracious welcome'
They met politicians, charity workers and others who have made a significant contribution to the Irish peace process and public life in Northern Ireland.
Mr Higgins and his wife were welcomed to the Royal Albert Hall by Prince and Princess Michael of Kent.
The president described the event as a "wonderful and historic occasion" in a "magnificent venue".
"This celebration, above all, is for the thousands of Irish people in this Hall who have made Britain their home or whose parents or grandparents did, as well as the friends, neighbours, relatives and in-laws, they have brought along," he said.'Deep friendship'
