I loved Enid Blyton as a kid, and I love Horrid Henry for end of the day storytimes because they read aloud so well. Enid's not dated well sadly but I remember going in to cover a class of kids, being told the fairly regular "if you've got a spare 10 minutes here's the book we're reading" and it was The Faraway Tree - and the kids were utterly utterly captivated by it even in a fairly streetwise before their time type of school.
I don't think Blyton ever deserved the public hanging drawing and quartering she got for a fairly log time; her books were a product of the era they were written in and got a generation of kids reading. Society's moved on since then - but that's not the fault of a long-dead author really is it.
Recommendation-wise - Julia Donaldson's books read aloud great for bedtime - I LOVE Stick Man and my old reception class adored Room on the Broom and of course Gruffalo's awesome. My favourite picture book (I'm a tad obsessed by good kids' picture books) of all time is Pumpkin Soup by Helen Cooper because of the quality of the illustrations and the discussion you can have about them. I also love Elmer (David McKee) to the extent I had picture cards I'd found of him framed and on my wall at one point. There are a fair few pretty turgid piles of poo out there though - so it's probably worth just picking things out of the local library rather than going out and buying them.
Hate the Very Hungry Caterpillar because it's done to death in schools. I also (and this is bordering on heresy for a teacher) don't like Where The Wild Things Are!
Books in chapters that you can read a bit at a time of are a bit harder to find - the younger level Roald Dahls I'd probably not be broaching with a class until about Y2 ish (my Y2s I had LOVED Charlie and the Chocolate Factory). He's always got his trademark of revelling in the total disgusting though - so it depends if you go there - just be careful over a couple of them as there's some potentially iffy language (one of the poems in his revolting fairy tales one and a more obscure Vicar of Nibbleswick story you'd want to pre-read and make sure you're happy with)
Dick King Smith's got some nice stories - but because he relies so much on dialogue they can be a bit slow to get started story-wise, when I've read them to a class (Y2 ish again) they've been a bit fidgety while he goes through his "using lots of dialogue to get the characters built with not much happening" thing. They liked Jenius by him (about a brainy guinea pig) and Hodgeheg when they got into it they enjoyed but it was a touch slower starting.
I still love Horrid Henry though - you can really lay it on with the voices and it can tame the most fidgetty rabid of classes and have them in fits of giggles!
Sorry - typing lots of this off the top of my head, most of my books are in the car boot and it's raining outside so I'm not going out there.
