Liz got her nickname "the Squeak" for her laugh which is so laden with ultrasonics that it shatters lightbulbs, is not permitted on aircraft, and is a prime cause of deafness in the East London bat population, it causes dogs major discomfort and brings Les Barker out in cold sweats. Once heard never forgotten.BTW the Leadbetter reference above, do/did you get "The Good Life"? the very Humourless (but brilliant comic creation by Penelope Keith ) next door neighbour was called Margo Leadbetter.
