Fergus Johnston, Dublin 2, writes:

I am baffled as to why you bothered to print such a stupid piece of writing as the letter titled ‘Organic Music’ on the eponymous composer B’ween Kay Li, (buíon céilí, or céilí band) supposedly written by his daughter Choona Day (Tune a day, I mean really…). It was a waste of an entire page, a plethora of drivle, bad bi-lingual puns and physical impossibilities (a butterfly beats its wings at a maximum of 20 Hz, too low for human audition; record it at 15rpm, and slow it down to 3 and 3/4, it disappears altogether…). If you’re going to print humourous articles, at least try to make them believable. If you prefer to make fools of your readers, save it for the April Fool’s Day edition. I’d prefer to have read something intelligent.
