For more than 30 years, Innfield had the privilege of presenting a daily three-hour music and talk show on national radio.

Since his schooldays, there had never been any doubt that this was what he wanted to do. He took the degree they wanted, and worked his way up from the bottom.

Radio - much more so than television, where Innfield has also worked as a producer - offers a very special level of contact with one's audience.

It was wonderful to be paid for doing something I enjoyed so much that I would probably have done it for nothing.

This episode looks at radio from the inside.
