The busker with the guitar (the good busker, with a real guitar who can really sing) was entertaining outside WH Smiths with his rendition of Robbie Williams' Angels.

Except he was not alone. Voices from aloft joined in – the two parties raising their voices to outdo each other.

Bemused shoppers were to be seen looking this way and that as they drew level, trying to ascertain where the additional voices were coming from.

The accompanying "choir" turned out to be a company of builders, heard but not seen, singing their little hearts out up on the scaffolding of a building opposite which is under renovation.

Green safety mesh hid them from view, but they could certainly be heard. And they knew all the words.

Their good-natured singing at an end they emeregd from a doorway, doorstep sandwiches in hand, to enjoy the company of passers-by (mainly female) and the continuation of the busker's street entertainment.

Builders. Tsk!

• Wished I'd thought of this one myself. Correspondent David Robinson, of Lynn, wonders out loud whether the money Lynn's Queen Elizabeth Hospital saves on electricity, when and if it gets the go-ahead for its own wind turbine, will offset the much-hated car parking charges.

It's a great thought, but what do you think?

Mr Robinson answers that one by predicting that the QEH will argue it needs the money-saving turbine merely to prevent car parking charges rising even higher!

I'd say there's not even a guarantee of that, and the hospital will want to separate the two endeavours completely.

Mr Robinson states that, in general, he favours turbines because we have to be prepared to use whatever resource to our best advantage. Good words.

"However, as the hospital continues to charge for payment and administers the car parking facility agrressively, surely now is the time for them to remove the charges if we give them permission for the turbine.

"We will hear from the QEH that they need this facility to prevent car parking charges from rising, and to use the revenue from the turbine to remove them will not be equitable.

"This will not placate the continued annoyance of the users of the hospital in regard to the charging regime. What many of us do not comprehend is the cost of collecting charges and the cost of adminstering these charges and penalties," says Mr Robinson. Eloquently put, hear, hear.

He suggests that approval of the hospital's application, and a similar one by Tesco, will lead to more similar proposals by those who will use these as precedent for their own financial advantage.

And Mr Robinson ends by asking that I give the people of West Norfolk what they want – the turbine to enable QEH to remove car parking charges. Done. See the editor's webline vote on the facing page and have your vote at www.lynnnews.co.uk

• After labours in the garden on Saturday we treated ourselves to a delightful day out in "summer" sunshine on Sunday at Little Walsingham's snowdrop walk, continuing on to The Globe on The Buttlands at Wells for a late lunch.

The unseasonal weather certainly seemed to have caught the staff there on the hop, overwhelmed, as they were, by sudden demand for meals and refreshment. In fact the delay was such that we skipped dessert and had an ice cream instead along the quay.

The woodland walk, alongside a spectacular carpet of snowdrops, was the reviver we needed. Talk about nature at its finest.
But what amazed me even more was the industry churning beneath our feet which had spun a fine embroidery of spiders' webs across acres and acres of fields.

The sun, low in the sky on the return journey, revealed this miracle of endeavour to us. A fine and continuous fleece of silk spun barely inches above the ground, gently rising and falling in a slight breeze, covered mile after mile.

How many trillions of spiders could it have taken to have performed this overnight feat, and how many trillions and trillions of flies did they hope to ensnare with such industry?

I was struck by the existence of so many insects in the ground beneath our feet which appear, for most of the time, to be invisible to us but must exist in such immense numbers in order to complete this incredible task.

Any entomologists out there who can give more information about this phenomenon?
