Going back to the first David Tennant story: (preferably sung a la Eartha Kitt)

CHRISTMAS INVASION
Nigel Parsons (1 Feb 2006)

I'm just an old fashioned girl with an old fashioned mind
Not sophisticated, I'm the sweet and "simple" kind
I want an old doctor who will make house calls at night
And a doctor who I know will care.

I want an old fashioned car, a cerise Cadillac
Not a blue Police-Box that has been to Hell and back
I want an old doctor who will make house calls at night
And a doctor who I know will care.

My new doctor looks a hoot
In his shirt and tie and suit
No more leather jacket or pullover.
No more cricket flannels too
But between both me and you.
Believe me, he's still quite the Casanova!

I've got a new Doctor
Who looks different from before.
Changed his whole appearance
But for why? I'm not quite sure.
I want my old doctor who will make house calls at night
And a doctor who I know will care.

There are several sounds that please,
Like those spinning Christmas trees
And plastic Santas playing Christmas carols.
But the sound that beats both them
Is the sound of our PM
As she gives it to the aliens with all barrels.
I want an old doctor who will make house calls at night
And a doctor who I know will care.

My new doctor came along when the TARDIS went quite wrong,
And aliens invaded in December.
And though he supports the right. His hearts weren't in the fight
Until he grew a brand new member.
I've got a new Doctor, Who can share my room at night
Spend the day in PeeJays. But then still put up a fight
I've got a new Doctor Who now, for better or for worse
Will take me round the Universe.
