Ali Fethi Ben Mohamed Ben Brahim Riahi, was a Tunisian singer and composer. He is the grandson of Sidi Brahim Riahi.
In 1938, Othman Kaak invited Riahi to join the radio, which was still in its infancy.
In 1950, the BBC devoted a complimentary program to him. The documents highlight, among other things, its decoration in 1954 by Muhammad VIII al-Amin of Nichan al Iftikhar.
