Ghassan's singing career began when he took part in "Petra" (1977), the popular musical play of Rahbani brothers. His main role in the play was the chief of the caravan who came from "Sour" (Tyr) to give their belongings to the queen.
Later, Ghassan Saliba took part in another musical play of Romeo Lahood called "Hikayit Amal" (Hope Story).
The general public knew Ghassan through his song "Ya Hilwi Shaarik Darih" which was a big hit at that time (early 80's). Few years later, Ghassan's success and popularity grew immensely and he was given a title (Julio Of Arabs).
In 1988, Ghassan Saliba starred in "Sayf 840" (Summer of 1840), a musical play for Mansour Rahbani, where he played the role of "Seif El Bahr", the sailor who returned to his country to fight against the Egyptian Army of "Ibrahim Basha" who was occupying Lebanon. Ghassan Saliba proved in that play to be the best to sing patriotic songs. Some of the patriotic songs of the play were "Lama3it Abwa' Essawra", "Zayyinou Essa7a", "Tawwalou Aleina", etc.
Also, the warmth of his voice was clear in "Gharibayn Wu Layl" which is one of the most famous Lebanese love songs ever.
