Keith, Camilla and David reminisce about their favourite childhood sitcoms, which leads them serendipitously onto today's interview. In the hot seat is Phil Maguire, pioneer of National Prison Radio – a station that broadcasts to more than 100 prisons across the UK. Phil reveals how it all began and why one prison officer has likened him to a second-hand car salesman. Good Charity Bad Charity is presented by Keith Davis, Camilla McGibbon and David Prest. It is produced by Dan Hardoon at Whistledown. Email: [email protected] #PhilMaguire #prisonradio #charitytalks #charitytrustees #charitydiscussion
