Some 140 volunteers, including singers, musicians and photographers, will join forces today to launch the first ever charity single to be recorded using Twitter.
Everyone involved in the project was sourced through the social networking site after organiser Brenda Drumm tweeted the idea a few weeks ago.
The Twitter Christmas Single will be available for download after the launch later today in Dublin.
The Neo-natal Special Care Unit in Holles Street was chosen through Twitter as the benefitting charity.
Brenda Drumm said she will tweet during today's event once the track becomes available to download through iTunes and Amazon.
