Elton or David ?

Fascination with Isabella Blow led me to read the article in the Sunday Times magazine about her recent demise after swallowing weedkiller ( at least I suppose that's what she did with it ) and spotting an obvious grammatical error in the card allegedly accompanying flowers at her funeral from Elton John and David Furnish ( let's hope I've spelled that right in view of my comments ), which reads : Darling Izzy the world will be a much less brighter place without you with love Elton and David .

They can be forgiven , grief being an awful thing, but I find myself noting such mistakes with irritation in a way which irks me . There are in fact grammatical errors everywhere today , and once (again allegedly) Grumpy Old Women like me ( though in fact I am actually quite Young ) have died out or ( perhaps better still , and less irksome ) Stopped Noticing , the world will be a different place .
I cringe every time I ring my daughter's school and hear the recorded message which contains a real clanger . I found myself unbearable to be around when I finally attended the school and found mistake after mistake on the walls and ( and this was the real killer ) in the teachers' handwriting . I hopped about a bit and muttered under my breath but looking round found it difficult to imagine finding anyone who would care really , and as I didn't want to cause any more embarassment ( to my long sufferening daughter ) than I already had simply by appearing at school at parent's evening , I sighed and went home . A lost cause .

And now this . Elton and David. In the Sunday Times .

PS spot the deliberate mistake in this post ?
