It is Perouze's aria from the second act of the opera of the same name, set to music by Theofrastos Sakellaridis and written by Giorgos Tsokopoulos, which premiered at the "Olympia" theater on 9/8/1911 by the "Ellinikon Melodrama" ("Greek Melodrama") troupe.
As Theodoros Chatzipantazis - Lila Maraka point out (see the book "I Athinaiki Epitheorisi", volume 3, Hermes Publishing Co. Ltd, Athens, 1977, p. 334, point 1): "In the spring of 1911, an unusual number of gypsy caravans appeared in the region of Attica. A large colony from Krakow, which impressed the Athenians with the cleanliness and general decency of its members, settled in the the neighborhood of Votanikos. (See related comments in the magazine 'Eikonografimeni', May 1911, p. 112). Another group settled at the Kifissia railway station, which became quite the fashionable thing among the aristocratic circles of the suburb. They were paid to play music and sing for them. Th. Sakellaridis himself, who wrote the music of the revue 'Panathinaia 1911', went on trips to the gypsy villages of the region of Attica with his protagonist Mrs. Reveka (the mezzo-soprano Olga Pikopoulou-Papadiamantopoulou-Valtetsioti) in order to get inspired for his melodrama 'Perouze', a play that talked about gypsies. (See his interview in the newspaper 'Athinai', July 17, 1911)."
In the magazine "Chronika" (3rd year', volume 2', No. 2, Constantinople [Istanbul] 15.08.1911, p. 24), in the regular column "Idika mas kai xena", reference is made (with the title "I Perouze") to the performances of the opera at the "Olympia" theater in Athens, which ends as follows: "Regarding Perouze's music, the composer himself says: My music does not hold the Greek citizenship. But it does not hold any other foreign citizenship. I must let you know that I am not one of those who believe that music has a homeland and borders. In my opinion, the only kind of music is original music."
