Gij Bent Aan De Beurt
The "Gebroeders Ko" are a partycouple from the Netherlands. Their real names are Ton Koopmans and Gerard Koopmans from Raamsdonksveer. Before they broke through (2002) with their party music they were construction workers.
They broke through in 2002 with the partysong "Ik heb een toeter op mijn waterscooter", and after that they made several other carnaval hits. In 2006 they hit the Top 40 chart for the first time with their own version of "Boten Anna" of Basshunter.
