I came across this recently uploaded blast from the past. I had completely forgotten John Thaw had appeared in this advertising campaign by Cadburys. The campaign also included many other TV pairings of the late seventies and early eighties, most probably only known to those in the UK; Mel Smith and Gryff Rhys Jones (British comedians); Paul Eddington and Nigel Hawthorne (Yes Minister, TV sitcom); Simon Cadell, and Ruth Madoc (Hi De Hi, TV sitcom) and many others. Hope you enjoy this little bit of TV history.
