In 1960, he was appointed the first indigenous Director of Broadcasting, and during his tenure he brought creative programme leadership to the Sierra Leone Broadcasting Service. Through him, Sierra Leone broadcasting was raised to the highest professional standards that became the envy of the region. His aim was to get the Sierra Leone Broadcasting Service to reflect more and more the true image of the country, its music, its songs and its talent. His influence was clearly distinctive in these area — he was the writer of the music of the Sierra Leone National Anthem.
He founded the National Dance Troupe and used it as a vehicle to encourage Sierra Leoneans to be proud of their rich cultural heritage. He led the troupe on many successful performances around the world. After the troupe's participation in the 1964 New York World's Fair, the following report was made: "This talented folk dance troupe imposed a vivid image of Sierra Leone on the minds of thousands of Americans when it took the New York World's Fair by storm in 1964." In fact, it was voted the best dance ensemble at the fair, and was presented with a gold plaque. In 1965, the troupe performed at the Commonwealth Arts Festival in London, where it had a great success. The following year, the troupe performed at the Festival of Negro Arts in Dakar, after which they did a four month tour of Western Europe.
The pioneering role played by John Akar awakened cultural consciousness among rural as well as urban populations, and firmly established Sierra Leone's place on the world cultural map. The immense potentialities of our indigenous cultures to rouse the people to action, cement national unity, and to open out to the wonderful realities of our times lay dormant, and if there is one things that John Akar achieved for his countrymen, it was to instill in them a sense of pride, a love for country and an awareness of their rich cultural heritage.
