Clark began his music career in the late 1960s, a few years after joining the Faculty of Law at the Jesuit University in Beirut without graduating there. He won several international prizes throughout his lifetime, such as the Menschen und Meer prize in Austria for his song Mori Mori, which granted him international recognition. His songs are characterized by romanticism and his distinct operatic voice. Besides Arabic (Lebanese) and English, Clark sang in Armenian, French, Italian, and Russian. He was famous for performing the score of popular cartoons in the 1980s, most notably for singing the Arabic theme song of the Japanese anime "
Grandizer." Clark was also the head of the union of Lebanese artists. He briefly performed as part of a trio called "The Golden Age" with his fellow Lebanese singers, Prince Al Sagheer and Abdo Munzir. He died on 20 February 2022, at the
Saint George Hospital University Medical Center in Beirut, at the age of 73. == Selective songs ==
