Six4one is a music group formed at a casting in November 2005 to represent Switzerland in Eurovision Song Contest 2006. Their song "If We All Give a Little" was written and produced by Ralph Siegel and Bernd Meinunger.

The group consisted of six members from different countries

Andreas Lundstedt from Sweden,
Tinka Milinovic from Bosnia and Herzegovina,
Claudia D'Addio from Switzerland,
Keith Camilleri from Malta,
Marco Matias from Germany (born in Portugal)
Liel Kolet from Israel.

The group were not created as a long-term manufactured band, but instead as "six strong voices" who could collaborate at the contest, and then go their separate ways after the final.
