105 Drive regulars Jessica and Carlie Foster are to present a special two-hour show this Sunday at 4pm.
The 17-year old twins attend the Hills Road Sixth Form College.
2-4-1 is part of their work experience on Cambridge 105 and features musical guest Lewis Mokler, who will play live, and talk about his recent tour.
Miss Cambridgeshire contestant Megan Borg will pop in for a chat. Carlie and Jessica will also meet Cambridge United footballer Josh Coulson.
As a community station Cambridge 105 can not only provide work experience, but also give students the chance to get personally involved in production, presentation, and other skills required for a career in the media.
