In July of that year they released their first single, with their first album following in October. At the end of 2001, Cypriot television asked them to be their participant in the Eurovision Song Contest 2002. They agreed and Theofanous wrote the song "Gimme" especially for the occasion. After finishing in 6th place they became famous in both Cyprus and Greece. One consisted of Constantinos Christoforou, Demetres Koutsavlakis, Philippos Constantinos, Argyris Nastopoulos and Panos Tserpes. In 2003 Constantinos Christoforou left the group.

One still plays reunion concerts occasionally in their local area, and the band members remain good friends.

One consists of Muk doing the vocals, John on the guitars, Gary on the drums, and Kevin playing the bass.

16) ONE, based in Melbourne are a 5 piece heavy alternative rock band similar to Tool, Deftones, Karnivool, A Perfect Circle, Butterfly Effect.
"Five musicians with varying experience, have come together to write good honest rock music. With an authentic thirst to create good heavy rock with plenty of flavour, we’re not about glamor, we’re about the music plain and simple. We hope you enjoy it, cos we’ve only just begun. Having just released their debut EP, the hard hitting and sonically diverse studio recording is just the beginning for ONE. The contrasting dynamic of the Melbourne-based 5 piece ranges from down-tuned chug-guitar with screamed vocals to subtle lyrical moments with layered atmospheric instrumentation. "
