If you go to the BBC Radio 5 presenters page you will find a list in alphabetical order – of first names. Bob Ballard & Brian Alexander under B for example. If you go in search of further information you will find one of those jokey questionnaires
Radio 4 on the other hand lists presenters in alphabetical order of surname – Clare Balding & Matthew Bannister under B. Further information consists of an old fashioned potted cv
I suppose I can understand something of the motive behind the lack of formal cv-type info about Radio 5 presenters – it is who you are & what you can do that really matter, not which university you went to. But I find I really would like to know a bit more. It is not as if they are shy about telling us about themselves in the general on-air chit chat
