Hi Jindabine,
I'm afraid that my facial recognition isn't too good now though one or two of the steely eyed killers in your photo seem familiar.
I notice that at the end of April '68 we were detached to Wittering for the Fighter Command disbandment flypast at Bently Priory. Quite a busy month in which I flew Hunters F6, T7, FGA9 and FR10, Meteor T7 and F8 and the Chipmunk. I have a photo of the parade with the aircraft overhead but all too small to pick out anything.
