When I was in my late teens and early twenties, the Radio 1 lunchtime show presented by the man formerly known as Peter Waters Dingley was essential listening. It wasn't non-stop chart music, neither was it too arty and Emperor's-new-clothesness for art's sake. It always seemed to be a healthy mix of much of the best Top 40 stuff around, plus a few interesting new names who weren't getting the exposure on other shows that they deserved - and it was all presented by someone who communicated his enthusiasm for the music instead of sounding like an aspiring games show host.
