Elena Patroklou S.O.S.
"SOS" was the Cypriot entry in the Eurovision Song Contest 1991, performed in Greek by Elena Patroklou.
The song is an environmentally-themed plea to the people of the world. Patroklou sings about the damage humanity has caused to the planet and that the SOS of the title is from the earth itself. While such topics are relatively common in popular music, they had not been raised as frrequently at the Contest.
