This poem is sung by Katniss Everdeen near the end of the 9th chapter of the book Mockingjay by Suzanne Collins.

Are you, are [bad word] to the tree
Where they [bad word] up a man
They say murdered three.
Strange things did happen here
No stranger would it be
If we met up at midnight
In the hanging tree.

Are you, are [bad word] to the tree
Where the dead man called out
For his love to flee.
Strange things did happen here
No stranger would it be
If we met up at midnight
In the hanging tree.

Are you, are [bad word] to the tree
Where I told you [bad word] 
So we'd both be free.
Strange things did happen here
No stranger would it be
If we met up at midnight
In the hanging tree.

Ooooohhh
ooooh

Are you, are [bad word] to the tree
Wear a necklace of rope,
Side by side with me.
Strange things did happen here
No stranger would it be
If we met up at midnight
In the hanging tree.

Oooooooooohhhh
oooooh

Are you, are [bad word] the tree
wear a necklace of rope
As you stand by me
Strange things did happen here
No stranger would it be
If we met up at midnight
In the hanging tree.
