Jethro Tull, "A Christmas Song"

Once in a royal David's city
Stood a lonely cattle shed,
Where a mother held her baby,
You'd do well to remember the things He later said.
When you're stuffing yourselves at the Christmas parties,
You just laugh when I tell you to take a running jump;
You're missing the point I'm sure does not need making,
That Christmas spirit is not what you drink.

So how can you laugh when your own mother's hungry?
And how can you smile when the reasons for smiling are wrong?
And if I just messed up your thoughtless pleasures,
Remember, if you wish, this is just a Chrismas song.
