Saoirse Ronan has proven that acting isn’t her only talent after singing a rendition of Fairytale of New York.
The actress joined Jimmy Fallon on his chat show where the pair of them sang the Pogues classic Christmas song.
Saoirse explained the concept of an Irish pub lock-in to Jimmy and the audience saying: “The whole town just goes to the pub, we lock the doors and have a drink and a singsong.”
When Jimmy suggests a Tonight Show lock in the pair decide to make it the real deal with the classic Irish song and some pints of Guinness.
