It seems that a certain Boris Johnson, a weighty panjandrum of further north, a mayor of some urban blight or other, received from his brother, 20 years ago, a Home Brew Beer kit.
Not knowing of the delights therein, he gave it back to his brother for his brother’s birthday. And got it back for his. And this kit has passed to and fro, from brother to brother for 20 years.

Obviously , and natch, this kit could not have been from BUNG HO, as it would have been put to it’s intended ambrosiacal use in the very first year, given the quality of the BUNG HO merchandise.
