Top 30 children's songs

According to the Independent the Government is planning to publish a 21st-century songbook consisting of the top 30 children's songs.  Alan Johnson will announce the move on Thursday and urges all schools to get pupils to vote for the songs they would most like to see in the book.

Any favourites to suggest?  Maybe Don't Give Up by Peter Gabriel for the teachers!

Edit: Here's the offical announcement on the Governments site.  I look forward to the support that is going to be given to teachers who can't sing - like me!
