Bertha, lovely Bertha, you are a lovely machine
Any anyone who works with you will know just what I mean.
Bertha, lovely Bertha, sometimes I thing you're a dream,
When we work out what you have to do,
You can always turn the goods out, always turn the goods out,
We can depend upon you.
A hidden gem of 80s TV that gets blank expressions when I mention it to people. Perhaps because there was only 13 episodes made and broadcast on BBC in 1985/6, sadly, whilst the DVD (and books if you can get hold of them) remains it was never repeated or revived.
