Well, Guest, you are allowed your opinion.
I failed to detect any humour,wit or musical talent or application whatsoever in Frank Skinner in the limited time I watched him on the programme in question. I'm often wrong however...convince me.
What I do know, for certain from personal experience, is that Pete Stanley has lots of musical talent, an ability to teach his subject to many happy receptive & keen students, and feel that he was badly represented by the BBC on this occasion.
I've known Pete since about 1963. worked with him full-time for a few years on radio, tv, recording studios,in many countries, and don't want to hear from you or anyone else that he couldn't teach a person to play banjo in four months to the standard required for the Winfield festival. It's an impossible task.
John Dowling couldn't do it either, nice man that he is, I'm sure. Frank Skinner simply hasn't got the application, knowledge of the subject or drive required.
The BBC are only interested in the programme, not the music.
