The godfather

Dumbledore said that we're the only ones
That can save Sirius Black
From his horrible fate
The dementors will eat his soul
He's gonna get the dementor's kiss
We've got to save Sirious
From something worse than death

But how can we do it?
When our teacher is a werewolf on the loose?
How can we do it?
When professor Lupin can bite anyone in sight?
How can we do it?
We don't have a time machine
How can we do it,
Hermione?

But you have an hourglass
You've got to use that hourglass
To go back to the past
To save a hippogriff
So Sirius Black can live

I saved Sirius Black, Hermione and me with a patronus
It was as big as can be
I didn't think I could do it
I thought I'd die
Why do I always think that I am going to die?

Dumbledore said that we're the only ones
That can save Sirius Black
And we did
