Tick tock goes the clock... 
And what then shall we be?
Tick tock until the day,

Tick tock goes the clock,
Even for the Doctor. 
Tick tock goes the clock,
He cradled and he rocked her.
Tick tock goes the clock,
Even for the Doctor. 
Tick tock goes the clock,
And now what shall we play?
Tick tock goes the clock,
Now that summer’s gone away. 
Tick tock goes the clock,
He cradled and he rocked her.
Tick tock goes the clock,
‘Til River kills the Doctor. 
Doctor, brave and good,
Turned away from violence,
When he understood,
