Y'see, the band have been invited to contribute some music to the next Harry Potter film (um, and the Bus Ride to School, or something), but word is that they might also make a cameo appearance.
Alex Kapranos told music channel VH1: "There's a section where there's a band of ugly sisters playing and I think, well... some members of Franz Ferdinand may be the ugly sisters in the band. There's an excitement and innocence about those films. I like how there's good and evil, and that's a clarity which is quite refreshing."
I find R Whites to be more refreshing, mind.
