Two things struck me right away. At around 8:52 minutes of the recording Peter French talks about mobile phone 999 calls. At one point he says: "So very often what you hear is the victim phoning up saying "I'm under attack. Please send the police" or ...". Listen to the section "please send the police":
Please and police are almost identical.
The second striking feature was French's pronunciation of the adjective adhesive in the phrase "self-adhesive envelope flaps" at about 2:03 minutes. Listen to that one as well:
One of John Wells's blog followers (= mallamb) points to the fact that Peter French drops the /h/ in this word. This, of course, doesn't turn Professor French into an aitch-dropper.
