The following comments and information were left on the Pebble Mill Facebook page:
Colin Fearnley: She was a guest on “Showaddywaddy Show” recorded in the 1980’s, the camera is an EMI 2001 which would correspond with that period and it looks like whoever is sitting bottom right of the camera is wearing one of the silly hats the crew and the audience were given. I was on racks and I think John Abbott lit it. Found in my 1980 diary, recorded in Studio A, Sunday 30th November and Monday 1st December. Kiki Dee inserts recorded on the Sunday, then live audience in for the Monday night. My hours 1030-2215 both days. John Kimberley on colour match And Peter Wood-Fisher on lighting desk (Q-File). The reason I remember it so well was that I had just escaped a very long course at Wood Norton!
