You can can win tickets to see Coldplay live in Paris on 9th and 10th September courtesy of an online French competition here
This is a NRJ radio contest, the same as the one for the Paris secret gig back in June. The questions you need to answer on the website are the same, and are multiple choice answers:
What's Coldplay new single?
Who painted the cover?
Where's the band from?
