As she recently told David Letterman, Jennifer Lawrence’s biggest fear is singing in public. Not death, not small, enclosed spaces, not tracker-jacker venom; singing in public. This posed a particular problem for the young star in ‘The Hunger Games: Mockingjay - Part 1’ because the script called for Katniss Everdeen to singing a song to her fellow rebels. And Lawrence had to actually sing it in front of the rest of the cast, a capella, with no voice double. The song, “The Hanging Tree,” is important to the movie. It becomes a rallying cry for the growing movement against the tyrannical President Snow and the rest of the Capitol. It needed to be real and heartfelt. And it needed to come from Lawrence.

After all that anxiety, though, Lawrence really doesn’t have anything to worry about; she’s got a lovely voice. She’s not going to win ‘American Idol’ or anything, but she fits the song, and what it means to her character, perfectly. And now you can listen to it over and over again while you wait for the next year for ‘Mockingjay - Part 2.’
