It's either a huge mistake or a brilliantly contrived piece of PR, but Britney Spears and Take That are both releasing an album called Circus (or The Circus) on the same day.
There won't be a Blur vs Oasis-style chart battle - Take That's album has already broken pre-order records, ensuring that it will go to number one by the end of the week.
But, as any chart historian knows, securing the top spot is no guarantee of quality - just ask Elvis, whose Suspicious Minds was robbed of chart glory by Rolf Harris's Two Little Boys.
So, who has constructed a better big top - Take That or Britney Spears?
