He is majorly known for the song "
Surangani", which attained cult status in the 1970s and 1980s in
Tamil Nadu. Although he is best remembered as a singer, Manohar had his sights set on acting from a very young age. He began acting in plays when he was a student at St John's College in Jaffna in the 1960s. Like many Sri Lankans of his era, Manohar came to India to pursue his higher studies. While he was a BA student in Trichy, he would go regularly to what was then Madras to try and get a role in a film. At that time all he could manage was a minor role in Maanavan, a 1970 film produced by M M A Chinnappa Thevar. Manohar moved back to Sri Lanka, where he first worked as a teacher and then decided to become a full-time singer. Sri Lankan music was undergoing a major transformation in the early 1970s when Manohar began performing regularly at major venues in the country. He was one of the pioneers of the country's new pop movement, where he combined Baila with elements of contemporary music. He sang with equal ease in Tamil, Sinhala and English. His rendition of Surangani was made popular across the island by
Sri Lankan Broadcasting Corporation (formerly Radio Ceylon), which in the 1970s had a loyal fan base in India. As soon as the song became popular in India, Manohar started making regular trips to Madras, and the roles in films came in slowly. Manohar got small roles in films including those that starred Sivaji Ganesan. He would go on to act in Telugu, Tamil, and Malayalam films, mostly playing the role of a villain. With his long curly hair, moustache and overweight frame, he fit the role of a ‘bad guy’ well at that time. When he was living in Colombo, the
Black July anti-Tamil riots hit the Sri Lankan capital and spread across the island. Manohar moved to India for a while and later shifted base to London, where he worked for the BBC's Tamil service. It would take two and a half decades for Manohar to act in a Malayalam film again, settling for a minor role in the Mammootty film
