In 1965 they had their first big concert in Bucharest. Their performance brought a collaboration with Cornel Chiriac to record some of their songs. The first songs they recorded were "Știu că mă iubesti și tu" ("I Know You Love Me Too"), "Dunăre, Dunăre" ("Danube, Danube") and "Bun e vinul ghiurghiuliu" ("Good is the Red Wine"). The same year also marked the beginning of their collaboration with Victor Suvagau, who went on to write many of their most famous songs, such as "Vremuri" ("Old Times"), "Și totuși ca voi sunt" ("And Yet I Am Like You"), "Nebunul cu ochii închiși" ("The Fool with Eyes Closed"), "Floarea stîncilor" ("Mountain Flower") and "Canarul" ("Canary").
