“The Hunger Games: Mockingjay - Part 1” just keeps on growing. On the one hand, it is the Thanksgiving weekend’s No. 1 holiday box-office giant, and, on the other hand, Jennifer Lawrence’s debut musical performance is climbing the Top 40 charts.

The Oscar-winning actress could be knocking on the door of the Grammy folks, too, for her haunting rendition of “The Hanging Tree” from “Mockingjay,” according to People magazine. The song comes up in the film when one of the members of Katniss Everdeen’s camera crew asks her to sing a song for him. The scene ends up being pivotal to the movie’s story, but the song by itself is both catchy and poignant. Now, BBC News has reported it has reached No. 29 on the Top 40.

Given the film franchise’s massive popularity, it may not appear all that shocking Lawrence’s amateur musical performance is climbing the charts: The movie grossed $11.1 million on Thanksgiving Day, Variety reported. However, it is an extraincredible feat given the actress’ apprehension about singing.

In an interview with Vulture, “Mockingjay” director Francis Lawrence (who is no relation to the star), revealed the actress was nervous about the singing scene. “I knew she didn’t love the idea of singing, but I didn’t realize how nervous she was until when we started the first take, and she was in tears,” he told the outlet. Luckily, the star was not so nervous that she couldn’t pull the scene off. 

The song was written by “Hunger Games” author Suzanne Collins with the help of the popular-music group, The Lumineers. It mirrors a similar song mentioned in the book, which Vulture does a great job of breaking down.

For those who want to sing along, the song goes like this:

Are you, are you

Coming to the tree

Where they strung 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 you

Coming 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 you

Coming to the tree

Where I told you to run, 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.

Are you, are you

Coming 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.

“The Hunger Games: Mockingjay - Part 1” will act as the first of a two-part finale to the franchise. The second film hits theaters in one year in Nov. 2015. You can see the movie in theaters now or listen to Lawrence’s musical debut below.
