Early episodes are lost. With the exception of two episodes from 1964, the episodes from October 1960 onwards survive intact (though sometimes only as telerecordings edited for export), and have been issued on DVD.
Haynes decided to part company with Nicholas Parsons after series 12 to avoid the pair being seen as a double act by the viewers. Tony Fayne, who had covered for him in series 9, returned to the show.
