At 7.20pm on Thursday night television presenter Dermot O'Leary started dancing and he didn't stop for a full 24 hours.
The man with strong Wexford links even kept moving during comfort breaks to raise as much money as possible for Red Nose Day.
Dermot pledged to do a 24-hour dance marathon in aid of Comic Relief 'when I was drunk' a few months ago and last week he did just that.
The BBC ran non stop coverage of the event and it was a joy to watch as Dermot joined at various stages by a range of other celebs busted a move or 20.
It began with guest dancers - flamenco experts, Cossacks and others - providing an ever-changing, jiggling backdrop to the affable O'Leary who bounced from foot-to-foot with varying degrees of energy depending upon the hour and where he was in his cycle of exhaustion.
Every new celebrity visitor or guest DJ was greeted with a grateful hug and every crowd member standing around the perimeter outside Broadcasting House in Central London were treated to endless autographs, selfies and friendly chat.
Spice Girl Geri Halliwell, Celebrity Juice star Keith Lemon and comedian Jack Dee were among the stars who have been dancing with Dermot, along with kids' TV favourite Rastamouse. He has also danced with Strictly 2014 champion Caroline Flack and Pussycat Doll Kimberly Wyatt.
Money raised will help give street children in Kenya a brighter future.
