I assume that is a bottle of Ramrod poured into a “half” of Special?
When I lived in London, I often used to see people in Youngs pubs pouring a bottle of Light Ale into Special.
I lived in Putney, just down the road from the Ram Brewery. A pint of Youngs Ordinary on a summer’s day down by the river was heavenly.
It was a sad day when the brewery closed. On the same day Sir John Young died, if memory serves.
