You've seen the DFDS Seaways Flashmob in celebration of Holland's National day, now take a behind the scenes look at the making of it.
This video gives you an insight into how and why the flash mob came about and includes interviews with some of the people involved, including ex Boney M singer, Reggie Tsiboe.
Background info - People travelling with Cross-Channel ferry operator DFDS Seaways (formerly Norfolkline) from Dover to Dunkirk last week were in for a bit of a surprise when 40 local students, from St Edmund's Catholic School in Dover, suddenly burst into spontaneous song, all dressed in orange.
The flash mob, organised by DFDS Seaways in conjunction with the Netherlands Board of Tourism & Conventions happened on board the car ferry to France, as part of the celebrations for Holland's national day, which takes place on 16 April in London's Trafalgar Square.
Also making a surprise guest appearance on the ferry was none other than Reggie Tsiboe, one of the lead singers of Boney M, who disguised himself as a DFDS Seaways chef, before joining in with the spur-of-the-moment medley.
The students performed the songs alongside Reggie, which included Queen's 'We are the Champions' -- sung in dedication to Queen's Day, the national day for Holland that is celebrated in April.
The flash mob event will be shown on big screens in London's Trafalgar Square on 16 April as part of the Holland Day celebrations.
