Following a promotional tour that brought Evridiki to Russia, Belgium, Belarus, and the UK, Cyprus competed in the semi-final of the Eurovision Song Contest on 10 May 2007.Cyprus' least successful result was in the 1986 contest, when it placed last with the song "Tora zo" by Elpida, receiving only four points in total.[5] Board Director Marios Mavrikios explained that the decision to select internally was in response to a controversy related to the previous year's process, which had used public voting.She had previously represented the nation at the contest in 1992 (with "Teriazoume") and 1994 (with "Eimai anthropos ki ego"), placing 11th on both occasions.[6][8] The song was written by Dimitris Korgialas and Poseidonas Yiannopoulos, and was the first Cypriot entry to be performed entirely in the French language.[21] The Eurovision Song Contest 2007 took place at Hartwall Arena in Helsinki, Finland, and consisted of a semi-final on 10 May and the final on 12 May 2007.[23] In preparation for the contest, CyBC aired five preview shows between 8 and 22 April, which showcased the promotional videos of the 42 participating entries and allowed viewers to vote for their favourite and win tickets to Eurovision.[25] All nations with the exceptions of the host country, the "Big Four" (France, Germany, Spain and the United Kingdom), and the ten highest placed finishers in the 2006 contest were required to qualify from the 10 May 2007 semi-final to compete in the final on 12 May 2007.[30][31] The backing vocalists that joined Evridiki on stage were Froso Stilianou and Marianna Gerasimidou, while the musicians were Korgialas, Dimitris Horianopoulos, and Giannis Skoutaris.
