Mario Rosenstock

Rosenstock first came to the attention of the Irish public playing the role of Dr. David Hanlon in the soap Glenroe in the 1990s. However, he is now best known for the popular Gift Grub segments which have featured on The Ian Dempsey Breakfast Show on Today FM since May 1999, which Rosenstock created alongside Paul McLoone, a radio presenter with Today FM and also frontman of the Northern Irish pop-punk/new-wave band The Undertones, which occurred in 1999 and when McLoone served as a producer for The Ian Dempsey Breakfast Show. Gift Grub is a series of comic sketches, impersonations and parodies that have featured Rosenstock assuming the personae of Bertie Ahern, Ronan Keating, Colin Farrell and Roy Keane amongst many others; he also provides the manic voice of Right Price Tiles radio spokesperson "Daft Dave".
