Excitement is building for Today FM's Big Busk for Focus Ireland, which takes place on the 11th of March.
On Gift Grub this morning, some famous faces leant their support to the cause.
Katie Taylor gave a rousing rendition of R.E.M's It's The End Of The World As We Know It, Johnny Sexton rapped, and Paschal Donohoe and Leo Varadkar performed a rather inappropriate version of Madness - House of Fun.
Catch all the Gift Grub fun by pressing the Play button above.
