The national final took place on 31 March 1989 at the ERT TV Studios in Athens and was hosted by Dafni Bokota. The songs were presented as video clips and the winning song was chosen by a panel of "experts".
It was later revealed that Mando was supposed to win the national selection; she was second, only one point behind Marianna. Mando took action against the Greek television station ERT because one of the jury members didn't vote. She won the ruling, but since the process was too late to reverse the decision, Marianna went to Eurovision.
