Some radio programmes may be eagerly awaited and avid listeners switch on just before the start. That may happen in a perfect world. The reality is different. People switch on the radio at any odd time. Perhaps they dread the silence of solitude or perhaps they do so as a habitual pattern of their life.

What the majority do is switch on at random times and rarely for a specific purpose such as to listen to the Budget speech. It is a lesson radio presenters should take on board. Many a time, a piece of music comes to an end but we are not told who the singer or composer is.

The same applies to interviews with interesting persons – at the end the presenter or interviewer thanks his guests using first names only and that is the end of that. Those who did not switch on at the start are left wondering who the guests were.

In my experience, all presenters introduce their guest at the start but do not take into account those who have tuned in later.

There is one notable exception: Charles Xuereb of Campus FM. He takes the trouble around half way to reiterate his introduction of his guest and briefly informs the listener about the subject of the programme.

Praise where it is due.

Hopefully his approach will be emulated by others.
