[3] Kostas Tournas and Robert Williams were childhood friends who started their musical cooperation in 1964 when they formed the group Teenagers.
[4] In 1967, they changed the name of the group to "Dinos and the X-Rays" but they separated soon after since Tournas had to go to the army and Williams went to Rhodesia where he stayed for two years.
[6] They also appeared at Elatirio presenting music influenced by Crosby, Stills, Nash And Young and featuring two new members, vocalist Nasia Sandi, and drummer Kostas Papaionannou.
[4] The group started recitals at a home which was owned by the grandmother of Kostas Charalambides, who was a salesman for the Greek record company Elladisk, a subsidiary of Dutch multinational Philips.
Charalambides provided a demo of the band to Christos Fasolas, who was working for Elladisk in the area of copyright law, and they eventually got a record contract.
On one side was the song "Anthrope Agapa"(Άνθρωπε Αγάπα, Mankind Love Each Other) and on the B-side was "Ela Ilie Mou" (Έλα Ήλιε μου, Come My Sun).
[6][7][8] Anthrope Agapa, ti Fotia Stamata (Mankind Love Each Other, Stop the Gunfire), is considered the first anti-war protest song in the history of Greek rock and was released during the junta years in Greece.
[6][8] In the spring of 1972 the band recorded a single featuring the songs "Aety" (Αετοι, Eagles) and "I Genia Mas" which became huge hits.
Later in 1972, they appeared at the Thessaloniki Song Festival where they played "Molyvies Fotografies" (Μολυβιές φωτογραφίες, Sketches), which they also released as a single with "Oses Fores" on the flip-side.
[7] Lefko was the last album of the group and included songs like "Ελένη" (Eleni), "Πες της μαϊμούς να μη με πειράζει με το δάχτυλό της" (Les tis maimous na mi me pirazi me to dachtylo tis, "Tell The Monkey Not To Disturb Me With Its Finger"), ""Ξημερώνει" (Ximeroni, "It's Dawn") and others.
