Look and Read: Dark Towers (Episode 2 - The Man in the Picture)

Come with me, yes come with me,
To Dark Towers.
Who can tell what we shall see
In Dark Towers?
Dust and cobwebs everywhere,
Footsteps on the winding stair,
Mystery is in the air,
In Dark Towers.
In the garden, in the hall,
Through the arch behind the wall,
Come and listen to the call
Of Dark Towers.
The educational segment features the songs:
Who's that standing at the top of the stairs?
Standing, staring at me.
Who's that standing at the top of the stairs?
Stop; we're S and T!
Ahh...S and T; I know that pair!
You can hide them everywhere.
There they are upon the stairs,
Waiting hand in hand.
Even in a heavy storm,
Together, they will stand.
See them coming down the steps,
Now, my heart goes pop.
Scared me stiff,
I'll just tell them: stop!
S and T; oh what a pair,
You can find them everywhere!
(Dog detective)
AND
I'm an apostrophe,
Come and take a look at me.
I'm not a comma; I'm not a full stop.
Don't put me on the line; I go at the top!
Watch how we use an apostrophe,
To shorten what you say to me.
That's how we use an apostrophe.
AND
You get more with Extra S!
