I'm trying to find the words for a song written in the early 70s. I only remember the chorus, which is:

Teesside is beautiful I'll have you to know
And the coals from South Durham make the blast furnaces glow
It's wonderful to see though the smoke's in your eyes
The flames from the oil refineries as they light up the skies.

One of the verses began:

Thank you Mr Edward Heath you're a very nice chap

And ended

But don't smile on South Durham or your teeth will turn black.
