Music on tomorrow night's The Late Late Show will be provided by Irish Women in Harmony with their brand new Christmas song, 'Together at Christmas', with all proceeds going in aid of Childline.

After the undeniable success of their cover of 'Dreams' by The Cranberries, The Irish Women in Harmony are back, this time with a Christmas single - to be released November 20th.

The supergroup's previous charity single raised over €250,000 for Safe Ireland.

The original song 'Together at Christmas' was written and produced by RuthAnne, with all parts recorded remotely by 30 of Ireland’s finest female musicians and a choir of young Irish girls after a call out was made to the next generation of aspiring female singers.

“It’s been such a joy to write and produce our original Christmas song ‘Together At Christmas’," says writer and Irish Women in Harmony founder RuthAnne.

"Hearing all the amazing Irish female talent come together again has been the best Christmas gift! We’re also thrilled to work in support of Childline, which is a charity very close to all of our hearts. Irish Women in Harmony is hoping ‘Together at Christmas’ will bring joy and festive spirit to the Christmas season, which we all need this year more than ever.”

To donate €4 now, text 'CHILDHOOD' to 50300 www.ispcc.ie/donate-now.

Ryan Tubridy has also revealed that Back to the Future star Michael J Fox will be among his guests on Friday's Late Late Show on RTÉ One, as well as former President of Ireland Mary Robinson.

The Late Late Show airs every Friday on RTÉ One at 9:35pm.
