I read with sadness and horror your report that a Yorkshire primary school has been forced to curb the children's playtime noise (School curbs playtime after complaints of noise, 18 September). The concentrated sound that young children make when set free from the classroom is one of my favourite sounds in the world. It contains laughter, joy, shrill screams of delight and indefinable currents of imaginative play. It is uplifting and life-affirming – music to my ears.

I liked your Student Cookbook (18 September) – just the thing I would have been grateful for when I came to London all those years ago. I'm going to send my copy to my nephew, who is about to go to university, but with one warning: shopping on a shoestring at Borough Market? Only if your shoes are made by Lobb or Jimmy Choo, I think.

Many thanks for the Student Cookbook. Most welcome ideas for this single pensioner.

Your obituary of John Freeborn (18 September) claims that the "Battle of Britain was fought by a disproportionate number of public schoolboys". In fact, they made up less than 10% of the total.

If 9.50am was always "cowboy time" (Letters, 20 September) then Batman was scheduled for "Dinner, dinner, dinner, dinner, dinner, dinner, dinner, dinner".

With this series of letters on the Bonanza theme tune, aren't you in danger of dumming down the letters page?

So the pope was expected to get an audience of 80,000 in Hyde Park (Papal bull, 18 September). Blind Faith got 100,000 in June 1969 at their very first gig.
