Kostas Skarvelis wrote hundreds of songs, of which over 200 (so far) have been identified in the 78 rpm discography. They were sung by the greatest singers of the interwar period such as Costas Nouros, Marika Franzeskopoulou (Tilitissa), Rita Abatzi (and her sister Sofia Karivali), Roza Eskenazy, Stellakis Permbiadis, Stamakos Vratzos Stratos , Antonis Dalgas, Grigoris Asikis, Costas Roukounas, Giannis Papaioannou, Apostolos Chatzichristos, Evangelos Sofroniou, Zacharias Kasimatis and others. However, he gave the "portion of the lion" to the great singer George Kavouras, who for a long period (1935-41) identified his voice with the excellent melodies and lyrics of Kostas Skarvelis. There are more than fifty songs recorded by G. Kavouras.
