Once upon a time, several [dozen] new year celebrations ago, the gang in our street were invited to what was billed as the final party [it wasn't---]by wee Colin at number 34. Colin was well prepared---he had a barrel of beer. Good beer too. The only fly in the ointment was, he'd forgotten that a foot pressure pump was essential in order to make our beer drinkable [primitive technology in those days]. Ah---what to do? The only pump to hand was a bicycle pump. It had to be made workable. The effect was attained by drilling a hole in the bung of a size that ALMOST was suitable to take the flexible adaptor of the pump. It was finally made operational using various tapes, elastic bands etc.. Each pint drawn meant a vigorous spell of elbow work in order to build a pressure; guess who ended up "barman"? Ach well I had my share---and we drank the lot among five of us----
