JACK & MAC, otherwise known as Jack Morrissey (Dundrum) and Brian McIvor (Slane), burst onto the scene in 1993 when they provided the cabaret marking Brian McIvor's exit from corporate life. They were successful in achieving that objective ("...if he wasn't going before tonight – he's really gone now!"). Over the years they have explored the darker side of the repertoire and discovered just why it remains dark. They are grateful to their audiences for helping them discover this insight at first hand.

Over the years, Jack & Mac have taken part in various concerts designed to raise money for charity. In the last 12 months they have raised €2,500 for the Royal National Lifeboat Institution and €3,000 for Concern. The money for Concern was the profit from the sale of their CD, They CAN’T be Serious.
