"Whether you’re a long-time Radio Caroline listener, or have found us over the years, you won’t want to miss this very special, one-off guest broadcast at the start of Ray Clark’s show tomorrow at 5 pm."
It's a 20 minute special. As it follows Johnnie Walker's final Radio Two show many online are assuming he will be Ray's guest.
I believe Glenn Adams is also in the studio. He would have only recently joined the station.
It is interesting that only one year after leaving Radio England he is telling the story that he left that station without notice and applied to Caroline subsequently. He didn't. There is a substantial recording of his Radio England show on 15-Oct-66 (he confirms here that is the date he left them) and throughout this he says that it is his final show. It is also clear that he knows he already has a job lined up on Caroline.
More recently ... this photo appears to be him and Tony B on the Ross Revenge ...
