Christy was joined on the programme today by Callum Taylor, who plays Caractacus Potts and Mike Bonner, who plays Grandpa Potts in the latest production of much loved musical Chitty Chitty Bang Bang at the Gaiety Theatre, along with Christine Wild from the Theatre School who is producing along with her daughter Rachel from the Rachel Wild Performers Studio. Callum also sang the beautiful lullabye Hushabye Mountain live in the studio for us.
