Check this out. Before a massive rugby match in France at the weekend, some of the top French Dirt Jumpers put a demo on for all the rugby fans. Lucas Stanus (the videograher) had this to say:

Stade Fran├žais VS Bayonne is a french TOP 14 premier league rugby match where we had the chance to admire a spectacular MTB Dirt show in the "Stade de France" in Paris. For the main french sport event, Five Solutions with the famous WRT Family were invited to propose to the 70,000 supporters an awesome Dirtjump show few minutes before the kick-off.

Here's Lucas' video. The speaking is in French, but action comes without a language.
