TR Mahalingam was the successor to MKTB & PUC. Several of his movies including Sri Valli, Naam Iruvar and Vedhala Ulagam were big hits. He made a comeback with Malaiyitta Mangai. Unwilling to act without singing, he went back to the drama tradition. He made occasional forays into films whenever he could sing - Agatthiyar being one of the most significant movies.

Several songs in Naam Iruvar were very good. Most of them are by Bharathiyar. Produced by AVM, who held the copyright to Bharathiyar songs then, it starred Sarangapani, B.R. Panthulu the famous producer of later years, Kumari Kamala ( a child - teenager star ), VK Ramasami ( an unbelievably thin VKR - He looks like Nagesh in this movie. )

Solai Malaroliyo - Unadhu
Sundarap Punnagaidhan

Karunamoorthi Gandhi Mahatma ( female singer )

Several others....


Vedhala Ulagam was produced by AVM again starring Sarangapani and Kumari Kamala. Some of the songs were

Odi Vilayadu Pappa
Kottu Murase?
Theeradha Vilayattup Pillai
Vidudhalai Vidudhalai ? ( DK Pattmmal, I think )

Malaiyitta Mangai has the famous "Senthamizh Then Mozhiyal". Produced by Kannadasan.

In Thiruvilaiyadal, "Isaith Thamizh Nee Seidha" was quite popular.

Agatthiyar has several songs by him
Namacchivaya Ena Solvome
Isaiyai Thamizhai Iruppavane

I think he acted in Raja Raja Cholan too but I am not sure.
