Six4One was a multinational pop group formed by legendary composer Ralph Siegel with the sole purpose of representing Switzerland at the Eurovision Song Contest 2006 in Athens. The goal was not to create a long-lasting group, but to bring in six strong voices that could collaborate together and then go their separate ways once the contest was over.
The group contained American, Maltese, German, Israeli, Swiss and Bosnian members.
They performed the song If We All Give A Little. As Switzerland finished in the top 10 the previous year, the group got a free pass to the final. They finished in 16th place overall with 30 points and recorded one album together before splitting up. However, they did lay the groundwork for other multinational bands in the contest in future years, most notably the group Genealogy which represented Armenia in 2015.
Swedish member Andreas Lundstedt went on to fame as part of the popular trio Alcazar, while Swiss member Claudia D'Addio took the stage name "Diamá", enjoying success in both Switzerland and Italy with songs such as "La Mossa (The Brush-Off)" and "Mare".
