What is this London Air-Accordion Society? It's a monthly lo-fi comedy club at The Green Man, Fitzrovia, London. Brilliant new acts support fantastic headliners, all hosted by comedian and air-accordion expert Helen Arney. How does one play the air-accordion? Imagine 'Guitar Hero' but with cardigans, berets and a soundtrack of 1940s French Chanson. Put Edith Piaf on the long player and hold your hands at pectoral-height, about 12 inches apart. Keep one hand steady and move the other gently in-and-out to imitate the bellows of a fine Fantini, or any other imaginary accordion of choice. Let's be honest here: it's a daft name for a nice comedy club but it works.
