Kirsty Young's castaway this week is the comedian and television presenter OW Jimmy Carr.

Despite being dyslexic, he got good enough A levels at RGS to study at Cambridge University. In his interview he mentions two inspirational teachers who taught him here at school, Mr Tim Claye and Mr Roger File.

After graduating with a degree in Political Science, and working for a major multinational company in London, Jimmy had what he calls an 'early midlife crisis', during which he lost his Catholic faith and was generally unhappy.

He attended lots of therapy courses in an attempt to find out what would make him happier and eventually set out on the road to becoming a comedian.

He quickly got a reputation for his fierce work ethic, heading up annually to the Edinburgh Fringe, touring with a new show virtually every year, and hosting many a Channel 4 panel show. Click here for his interview.
