Country music star Nathan Carter is performing a special charity concert in Castlerea Prison tonight.
It's taking place in the church which is located within the prison walls.
Nathan is performing in front of staff and invited guests from the local and surrounding communities.
It will also be recorded and streamed for the 389 prisoners in Castlerea, who can watch in on their cell TV channel from tomorrow.
The one-of-a-kind concert is to raising vital funds for three charities - the paediatric ward in Sligo University Hospital, Roscommon Youth Services and Mayo Roscommon Hospice.
An Irish Prison Service spokesman said: "The profit raised from this exclusive event will be directed towards the charities.
"The paediatric ward in Sligo University Hospital will benefit from new baby monitors and equipment, while Roscommon Youth Services will use the proceeds to support a bursary program for youths aged 10 to 24.
"Additionally, Mayo Roscommon Hospice will receive contributions towards the sensory and healing garden in the newly developed Roscommon Hospice."
Governor of Castlerea Prison, Theresa Beirne, from Boyle, spoke to our reporter Eoghan Murphy about holding the event.
Nathan Carter spoke to Eoghan about the unique experience.
