What is the Doctor Who Night Terror's song?

Answer 1

At least, I got this off the episodes.

tick tock, goes the clock, and what then shall we see?

tick tock, until the day, that thou shalt marry me,

tick tock, goes the clock, and all the years they fly,

tick tock, and all too soon, you and i must die,

tick tock, goes the clock, we laughed at fate and mourned her,

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, tick tock, goes the clock,

tick tock, goes the clock,

doctor, brave and good, he turned away from violence,

when he understood the falling of the silence,

tick tock, goes the clock, he cradled and he rocked her,

tick tock, goes the clock, til river kills the doctor,

tick tock, goes the clock, and all the years they fly,

tick tock, and all too soon, your love will surley die,

Answer 2

The song playing during the Night Terrors episode of Doctor Who is "The Pink Windmill Kids" music from the popular 1980s British children's show "Emu's Pink Windmill Kids".
