Yep there was. It went:
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.
Clicking in the day and flashing in the night,
Your computer is shining brightly,
Some people say you've a mind of your own,
And I think that's very likely, likely.
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.
It's also possible to order the Bertha DVD for 4.99. Think that may be done pretty soon.
