Janet, when was he singing his song to you?

Roald Dahl's Charlie and the Chocolate Factory is a 1964 children's novel so he would have been 58.
One of the songs\poems was

Dear Friends, We Surely All Agree

Dear friends, we surely all agree
There’s almost nothing worse to see
Than some repulsive little bum
Who’s always chewing chewing gum.
(It’s very near as bad as those
Who sit around and pick the nose).
So please believe us when we say
That chewing gum will never pay;
This sticky habit’s bound to send
The chewer to a sticky end.
