Hozier, Jamie Heaslip and Hometown are among the special guests to hit St Stephen's Green Shopping Centre this Thursday, as 2fm broadcast live from the Benetton store.
As part of their Xmas appeal in aid of the ISPCC, the hosts of the station will be doing their thing in the shop window, and have lined up a galaxy of stars to help them along.
Among them are Hozier - who also headlines the Jingle Bell Ball later this month - and Hometown, who jumped straight into the top five with their debut album last week. The Riptide Movement are also among the musical guests featured, and familiar faces from the world of sports and broadcasting will be there in the shape of Jamie Heaslip and Vogue Williams.
The broadcast, running for 12 hours from 7am to 7pm, aims to rise funds for the ISPCC.
