Irish singer-songwriters Christy Moore, Sinéad O'Connor, Lisa Hannigan and Hozier have been honoured by An Post in a new set of stamps, with a donation from every booklet sold going to the Music Industry Covid-19 Emergency Relief Fund.

Designed by Dublin-based Shaughn McGrath Creative, the stamps celebrate the artists' participation in the Glastonbury Festival over the years and are now on sale.

As part of the launch, Christy Moore, Lisa Hannigan and Hozier were joined by spoken word artist Natalya O'Flaherty - performing Sinéad O'Connor's 3 Babies - for a virtual show from Dublin's GPO.

The show premieres at 8pm tonight at anpost.com/festival and fans will be able to watch the performances for the next four weeks.

Christy Moore in the GPO - "To be invited here to sing is one of the great privileges of my working life"

Speaking ahead of his performance, Christy Moore said he wished that his grandparents were alive to see him on a stamp and performing in the GPO.

"To be invited here to sing is one of the great privileges of my working life," he continued.

Hozier - "To be on an Irish stamp is such an honour"

Hozier said it is "such an honour" to feature on an Irish stamp "in such incredible company".

Lisa Hannigan said appearing on a stamp meant so much after the challenges of 2020/21 and that she is looking forward to going back on the road.

Lisa Hannigan said she could not believe she had been chosen to appear on her own stamp

"Part of the rhythm of your life, like the seasonality of it, [is] writing and touring," she added. "Touring is nourishing and it fills you up to go and write songs. I've missed that part of the cycle for a year now."
