A slight digression and perhaps useless trivia--my forte I might add:
RK taught vocal music to Smt Kamala Narayan(nee Kumari Kamala) in the early fifties--our family was/is still in touch with her and her family- Kamala was living with her mother and sisters in a nice modern bungalow in a lane called De Monte lane connecting San Thome High Road to the Beach.During the summer months when myself and my sister came to Madras,along with our cousins used to visit them and play cards,carrom etc. Generally when she did not have dance rehearsal with Vazhuvoor Ramiah Pillai(the dance rehearsals were rigorous and frequent and the practice schedules were tight because of Kamala's Dance commitments),RK would come for tuition.(he used to live in Nadu Street in Mylapore (as I recall)--not far from San Thome)
One day in late April.he came as per the schedule in one of those hand-drawn rickshaws to teach- in 102 degree heat-that was the day we had all planned to have fun,visit the Marina Canteen,movies etc--big deal in those days for us kids!!!. We had gathered in Kamala's house and were playing-when RK arrived Kamala was in no mood for tuition and literally pleaded with RK to reschedule much against her Mom's will .Somehow she "sweet-talked" RK saying we have come from Bombay etc etc. RK was very understanding-Kamala was sweet enough to send him back in her car--he was a good teacher--very patient(ofcourse Kamala's celebrity status may also have been a factor!!)I think Kamala has given a record Kaddana Variki in Thodi(I think this was taught by RK!!)
Seriously though as CACM pointed out his early career was dwarfed by the giants--SSI,MMI,GNB and did not have a mentor like KVN had (Ariyakudi/Palghat Mani Iyer) and TNK had in SSI. As they say One has got to be in the right place and at the right time!!!
