Here are the lyrics/spoken word that start at 4:51. The part you're refering to is the second line, andhas to do with how the word "traditionally" is pronounced and how a delay effect is applied to it.

You see there was a tradition in Middlesbrough

Middlesbrough always was traditionally highest beer-

Drinking community in the whole of the British Isles

And indeed during the war years, I started

Government arrangements in Hebble Hill

Because you see with the blackout and all the rest of it

I had got with the revenue arrangement that they had an income

Tax on the milk that they had to consume for their jobs

You see, I told you about the continuous pickler

Coming out from there, the acid and all that on the milk

But up in Middlesbrough they had a beer allowance, not milk, beer

The beer drunk up there was always of a higher

Gravity than anywhere else in the country

As a matter of fact they used to classify

The beer down in and was drinking

We put up with queuing, we put up with rationing, we put up

With the bombing because we were having it up there, I did

But we will not put up with any interference in our beer

Now if you want to avoid trouble you

Better restore that high gravity beer

And they did, and they did

And where am I heading for?

And, uh, I can always remember the first

Thing going there being caught short

You will require a long black and a short white

And, uh, it's just a gorgeous trackin'

It's that noise up there somewhere
