Hi Richard
Re Crucial Brew.

I think it was something like 12% volume and nothing has equaled it since in a can.
Special Brew was nothing in comparison and nether are the 9% cans like the are ones on sale these days.

Crucial brew was drunk by the homeless. has high 9% cans of Tennant and skol still are to this day>

If my memory serves me right

"There was a tee shirt once that had a picture of a tramp on the front and the tramp had a halo of a glow all round his body and he held a loft a can of Crucial Brew and the caption on the tee shirt read.

In big Red Letters                         "Crucial Brew
                                                          Ready Break for tramps?
Re the Ready break porridge oats breakfast , advertised on television at about the same time has Crucial brew was on sale.

The advert with glowing kids going to school in a snow storm?
The tee shirt sold in great numbers at Carnaby Street. But ther tee shirts were banned by the then outraged authorities at the time.

Regards Pierre.
