Happy Christmas! Santa must be here!

It's time to think about eating, drinking and the presents under the tree on Christmas Day. But let's also think of all those who do not have enough to eat at this time of year. And that's more than one billion people — a huge and shocking number. The great Bob Dylan has been thinking about all this, which is why he's donating the royalties from his new album to the World Food Programme, Crisis and Feeding America. As he wrote on his website, "It's a tragedy that more than 35 million people in this country alone — 12 million of those children — often go to bed hungry and wake up each morning unsure of where their next meal is coming from." So, before we go to Bob's house party, let's promise to help those in need.

Now it's polka time, because it "Must Be Santa". Happy Christmas!
