As befitting the times, the humour in this special is very "safe" material, with any slight innuendo dressed up for a family audience. Perhaps the raciest gag is Max Bygraves saying he was a nun in The Sound of Music for two years but got thrown out for having "a dirty habit".
However, production footage shows that Max was telling moderately dirtier jokes to the audience during the untelevised break (albeit still very tame by modern standards), with audio of him saying: "Two bottles of milk on a doorstep, one said 'I feel fresh', the other one said: 'What a pity, I'm sterilised.'"
