"Ruby" is a song by Kaiser Chiefs which is not about anyone in particular, just a name they made up. In an interview with contactmusic.com, Andrew Whitey White said: "It's obviously about something but from our perspective it's not written about anybody. But if you know someone called Ruby, it's about them. It's honestly that simple."
In a ultimate-guitar.com interview, White said: "'Ruby,' to be honest, is our most radio-friendly song. That is that kind of the pinnacle of songs and a pinnacle of songwriting. We worked really hard for a great melody that's catchy. It's got everything in there. With the album, it flows much more. The first album was like a collection of singles, we thought. It was like a greatest hits. Big, fat, catchy songs. The second album kind of flows more. We wanted to do a much bigger, better, louder, stronger album. We wanted to create more than a collection of great singles. We've got 5 or 6 singles in there, but they're hidden. They kind of flow into other songs.
This was the Kaiser Chiefs first UK #1. (thanks, Edward Pearce - Ashford, Kent, England, for all above)
This won the 2007 Best Video prize at the 2007 Q Awards. The video sees the band perform "Ruby" in a desert, as around them a tiny CGI city builds itself. It was directed by Swedish production company Stylewar, who were also responsible for the band's "I Predict A Riot" video.
