Despite being relatively unknown in Greece, the duo entered the national final to be Greece's representatives in the Eurovision Song Contest 2001 in Copenhagen, Denmark with the song "(I Would) Die for You", written by Nikos Terzis with lyrics by Antonis Pappas, placing joint first, but being named the winners by default as they had won the public vote. The song placed third in the actual contest with 147 points; although equaled by the 2004 entry, it was the best placing Greece had ever received until Paparizou won the contest as a solo artist in 2005. The song went on to become their biggest hit in Greece, reaching Platinum status, while it peaked at number three in Sweden and Greece, and charted elsewhere. Antique's success in the contest led to them earning recognition in Greece and working there for the rest of their career.
