Why does Classic FM hire ex-BBC presenters?

 I was delighted when John Humphrys stopped doing BBC Radio 4 Today programme when he was so obviously way past his best.

But why Global’s Classic FM management thinks he knows enough about classical music to present for them escapes me. Or maybe the automated selection of “the world’s favourite music” doesn’t require any expert knowledge.

Yet quite a lot of their regulars do know what they are talking about - so how do I get a job with Classic FM???
