Ellinikós Telikós 2010 Seven acts competed on 12 March 2010 in the
Greek National Final. The song was performed fourth in the final by Alkaios along with "Friends", which consisted of musicians Gogua Iakovos, Evgenios Buli, Petros Zlatkos and Anastasios Kanaridis who acted as backing vocalists and backing dancers, along with Lazos Ioannidis who plays the
lyre during the song's break. At the end of voting, "Opa" was revealed as the winner. The performance in the contest differed from the one in the national final. Alkaios passed the first semi-final, coming in 2nd place, behind Belgium, and went on to perform in the final on 29 May 2010. In the end,
Greece came 8th, with 141 points, while for most of the duration of the voting,
Greece was in the top 3 (and even came 1st for a while). It was the highest placing non-English song of the contest. "Opa" was the most popular song for the jury in the United Kingdom, being awarded the full 12 points. Following Eurovision, "Opa" was formally adopted by
Bournemouth University in the UK as their fieldwork anthem on the excavation programme throughout June and July 2010. ==Track listing==
