Rainbow sheep?

Hard to believe but this report in The Times seems to be true:

"TRADITIONAL nursery rhymes are being rewritten at nursery schools to avoid causing offence to children.
Instead of singing “Baa baa, black sheep” as generations of children have learnt to do, toddlers in Oxfordshire are being taught to sing “Baa baa, rainbow sheep”.
The move, which critics will seize on as an example of political correctness, was made after the nurseries decided to re-evaluate their approach to equal opportunities...
In keeping with the new approach, teachers at the nurseries have reportedly also changed the ending of Humpty Dumpty so as not to upset the children and dropped the seven dwarfs from the title of Snow White."

What will they do about Little Miss Muffet? Or Goldilocks and the Three Bears?
