Balasubrahmanyam, 67, who was last heard in 'Chennai Express', sang a line each in 15 languages receiving the award at the International Indian Film Festival of South Africa (IIFFSA).
Although the nature of his illness was not disclosed, organisers said plans were being made for the singer to return home today. A dinner event, which was supposed to held tonight with him, has also been canceled now.
IFFSA is aimed at promoting cultural links among the Indian and South African film fraternity. Awards were made in various categories for regional language films from both countries.
Opperman said IFFSA was very significant in that the recognition of the unique Afrikaans film industry in South Africa by India confirmed that this community still had a major role to play in the country.
