Taylor Swift fans will certainly want to see her in the movie version of Cats, which opens around Christmas…but they will get an extra treat as Tay collaborated with Andrew Lloyd Webber to write a new song for the movie called “Beautiful Ghosts. The song is sung by both Francesca Hayward, who plays Victoria in the movie, and by Dame Judi Dench, who is "Old Deuteronomy." Best of all for Tay fans, Taylor sings it too over the closing credits. Watch the video as Taylor talks about writing the song as well as a little taste of what Beautiful Ghosts is all about.
